This week's EYE ON NPI is teamwork makin' the dream work - a collaboration between our favorite module makers Raytac (https://www.digikey.com/en/supplier-centers/raytac) and our favorite Bluetooth Low Energy designers, Nordic Semiconductor (https://www.digikey.com/en/supplier-centers/nordic-semiconductor). Together they've created what we think is the best nRF52840 module, the Raytac MDBT50Q-1MV2 (https://www.digikey.com/short/t8hvw1bt). Historically you've had to pick this up direct from Raytac, but now it's stocked by DigiKey which is excellent news for anyone who wants to integrate the powerful nRF52840 with little fuss. The Nordic Semiconductor nRF52840 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF52840-QIAA-R/7725407) is not a new chip, we've been selling the Feather nRF52840 (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4062/9843410) since 2019 and the chip itself was announced in mid 2017 (https://www.nordicsemi.com/Nordic-news/2017/05/Nordic-Semiconductor-introduces-latest-nRF52-Series-SoC). It builds on the popular nRF52832 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF52832-QFAB-R/6051565), a chip with an Arm Cortex M4-F / 512K Flash / 64K SRAM, but with a ton more memory: the '840 has 1MB Flash and 256K SRAM. It also comes with native USB device support, which is new to the nRF series but makes product design easier because DFU and computer-interfacing doesn't require a second chip. The only challenge is that the nRF52840 itself is in a funky QFN package with pads underneath, and multiple rows, which requires either very fine traces, 4-layer boards, plugged vias, or a combination, in order to get to the 'inner' traces. Also, you have to get your antenna tuning right - even though the nRF is very forgiving, it's still extra effort! That's why at Adafruit we have been using Raytac's MDBT50Q-1MV2 Module (https://www.digikey.com/short/t8hvw1bt) for years, in our Feather nRF52840 (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4062/9843410), ItsyBitsy nRF52840 (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4481/11497502) and CLUE board (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4500/11594501). We like that it pick-and-places cleanly and easily on 2-layer PCBs with 8/8 rule DRC, comes with certifications, and has a couple different built-in antenna options, all tuned and ready. In particular, if you want a larger and/or external antenna check out the MDBT50Q-U1MV2 (https://www.digikey.com/en/products/detail/raytac/MDBT50Q-U1MV2/13968055) but we like the chip-antenna version the most. Either way, the module footprint is much easier to work with - you still have pads underneath but they're large, and you can easily fit vias in the unused spots. Just make sure you keep ground clearance around the antenna if you're using an on-module version. If you need tips on schematic and layout, just use our open source hardware design files to guide you - or check Nordic's devZone (https://devzone.nordicsemi.com/). If you've wanted to use the Nordic Semiconductor nRF52840 chip (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF52840-QIAA-R/7725407) for your ultra low-power Bluetooth LE products, but have hesitated due to the effort of integrating the QFN chip, we can't recommend the Raytac MDBT50Q-1MV2 module (https://www.digikey.com/short/t8hvw1bt) enough! And now that it's for sale through DigiKey, you can pick up some at a great price. Order today and you can BLE-ify your next design by tomorrow afternoon.

This week's EYE ON NPI is more like an "EYE ON Ladyada's Desk" because while the ESP32-C6 has not yet been featured by DigiKey on their New Products Page (https://digikey.com/new) we're starting to spend a little time checking out this new Espressif chip - the ESP32-C6 series - and the ready-to-use modules available from DigiKey, such as the ESP32-C6 WROOM (https://www.digikey.com/short/8vj302rf). We use the Espressif family of chips (https://www.digikey.com/en/supplier-centers/espressif-systems) in tons of our designs: they're inexpensive, powerful, have excellent low-power sleep modes, and all come with fast and secure WiFi functionality, so they make for excellent IoT devices. Starting with the ESP32 in 2016, a follow-up to their 'accidental microcontroller' the ESP8266, Espressif has focused on Tensilica-based microcontrollers with built in WiFi and/or Bluetooth radio. By combining the silicon for radio and processor, they've been able to come in at disruptively-low pricing (https://en.wikipedia.org/wiki/Disruptive_innovation) - with chips ranging from $1-$3 and modules from $2-$6. Over the years they've branched out to include improved BLE, native USB, and many other peripherals like CAN and TFTs. They've also dabbled in RISC-V, adding a co-processor to the ESP-Sx series and finally going 'full RISC-V' in the ESP-Cx series. Now, with the C6, they're adding a new protocol to the mix: in addition to updating to WiFi 6 and BLE 5, the C6 also can talk 2.4GHz 802.15.4 which means it can communicate with Zigbee devices (https://en.wikipedia.org/wiki/Zigbee) including Thread and... Matter (https://en.wikipedia.org/wiki/Matter_(standard)) an open-source connectivity standard for smart home and Internet of Things devices from the Connectivity Standards Alliance (https://csa-iot.org/) formally the ZigBee Alliance. Matter is, hopefully, not just the latest, but the last attempt at creating a unified standard for home/business/industrial IoT and automation. It is a higher level protocol that runs on top of WiFi, BLE, or Thread - Thread being a replacement for Zigbee that also runs on 802.15.4 radios. That means that if you want to create a Matter device, you can use any of the three transports (https://learn.adafruit.com/alltheiot-transports) supported by the ESP32-C6: WiFi is medium range, medium cost, high power, medium complexity and high data rate: once you set up the access point, and as long as it's plugged into the wall, it tends to work very well. BLE is lower range, low cost, low power and medium complexity since you still need to pair to another device. Thread/ZigBee is medium range, low power, low cost, and high complexity since you need a gateway to use. As of this post/video, the Matter API for Espressif chips is only available through the ESP IDF SDK (https://github.com/espressif/esp-matter), and not in Arduino yet, although there is an open issue being worked on (https://github.com/espressif/arduino-esp32/issues/7432). However, if you aren't up for using the ESP-IDF for programming, you can check out ZeroCode (https://zerocode.espressif.com/) Espressif in-browser code generation, compilation and uploading system. At this time only '2-chip' setups are available for code generation, the 'bare' ESP32-C6 support is coming soon, but we tried out the IoT ExpressLink configs (https://www.espressif.com/en/solutions/device-connectivity/esp-aws-iot-expresslink) which have UART commands for setting up and tearing down the Matter device. After filtering for ExpressLink, we selected the C6 Mini module we have on our Feather prototype. A schematic is generated to show how the module will need to be wired for the UART access. Then you can program it directly in the browser. The unique Matter identifier is turned into a QR code: you can scan this with your mobile phone to add the device to your home's Matter-hub. Finally - check out the AT command reference (https://docs.aws.amazon.com/pdfs/iot-expresslink/latest/gettingstartedguide/expresslink-gsg.pdf) for how to start the Matter subsystem and send/receive data. As Thread/Matter gets adopted as the next-gen IoT transport protocol, the Espressif ESP32-C6 (https://www.digikey.com/short/8vj302rf) is positioned to be the perfect module for fast integration and low cost. With pre-certified and encased modules, plus a ready-to-go SDK, you can spin up a prototype product in just a couple days. We recommend starting with the ESP32-C6-WROOM-1-N8 module to start, with tons of flash memory, you can always downgrade if you end up only needing 4MB of Flash. There's also an affordable ESP32-C6-DevKitC (https://www.digikey.com/en/products/detail/espressif-systems/ESP32-C6-DEVKITC-1-N8/17728861) that has all the basics on already for instant bring-up. Order from DigiKey today to get your ESP32-C6's by tomorrow afternoon so you can be ready for the future of IoT with WiFi, BLE 5 and Thread/

This is a USB HID device that is set up to play media and adjust the volume of your speakers. Underneath the knob is a NeoPixel strip that changes color whenever it’s turned up or down. You can single-click to play and pause media, double-click to skip to the next track. If you long press, it’ll mute the speaker's volume. The electronics are housed in our 3D printed snap fit enclosure that features a new design. The knob features a built-in LED diffuser with textured knurling on the outer edge. We used the filament swap technique to make a multi-material print so there’s no need for a multi-extruder. Just use white PLA filament to diffuse the LEDs.

We're working on an updated version of our soil sensor, and thinking of making a version that has a coin cell battery on the back. However, we can't use the common 'retainer' style of CR2032 coin cell holder because we will have traces on the back that would make routing hard. Let's search for a battery holder that comes on tape - so we can pick and place it - but is SMT and is a proper holder that has small positive and negative pads. We want a slim and unobtrusive style if possible, and low cost so we can keep our BOM minimal.

This week's EYE ON NPI will take you to Infinity and Beyond, with Infineon PSoC™ 4000T Microcontrollers (https://www.digikey.com/en/product-highlight/i/infineon/psoc-4000t-microcontrollers) and the CY8CPROTO-040T eval board (https://www.digikey.com/short/qhfjbt39) specifically designed to get you started with the 4000t series microcontrollers and using the Infineon-neé-Cypress CapSense technology for capacitive touch buttons and slider. The Infineon PSoC™ 4000T series of microcontrollers are based around the classic Arm Cortex M0+ core, running at 48 MHz and with 64K flash, 8K of SRAM. So, a great microcontroller for simple products/white goods that don't need USB or a graphical display, like headphones, rice cookers, tea kettles or electric toothbrushes. The chip is optimized for capacitive touch sensing, with timers and lots of capsense inputs, but not a ton of other peripherals: there's only two serial blocks that can be configured as I2C/UART/SPI, and no ADC/DAC or USB or CAN. As long as your product is intended to be low-cost, and simple, that's probably just fine! The real star of the show on these chips is the CapSense peripheral (https://www.infineon.com/cms/en/product/microcontroller/sensing-controller/capsense-controllers/capsense/), which has up to 16 inputs - out of 21 GPIO! These can be configured as "CSD-type" self-capacitance sigma-delta buttons or sliders, or as "CSX-type" mutual-capacitance X-Y grids (https://www.youtube.com/watch?v=SOOZII8cvT4). Capacitive sensing is great when you want products that react to touch without needing large and breakable tactile switches. For example, touch sensors on headphones can determine when they are inserted into the ear and when a finger is touching the body to pause or adjust volume (https://www.infineon.com/dgdl/Infineon-The_touch_sensing_HMI_in_wearable_and_IoT_devices-Whitepaper-v01_00-EN.pdf?fileId=8ac78c8c8a44f57b018a5f0711243a0f). Unlike buttons or encoders, there's no risk of eventual mechanical failure, rending a product useless: with a smooth clean surface you can still provide a full UI with low cost and maintenance. The Infineon PSoC™ 4000T series comes with the 5th generation of CapSense, which features autonomous DMA function in deep sleep, great responsivity, and moisture resistance. One downside of classic capacitive touch solutions is false 'ghost' triggering or sluggish 'touch blindness' when the touch surface is wet. This is a common issue with products that end up being used in a kitchen, bathroom, laundry room, while exercising or outside. That's because droplets of water have capacitance on the order of the human finger and so each droplet looks like a touch. Most capacitive sense implementations have a slow self-zeroing drift calibration procedure, but they don't handle sudden water sprays. CapSense 5th gen, by comparison, will maintain the same raw capacitive count even when there's spray, mist or droplets! Another neat feature is the autonomous sensing block, which allows ultra low deep sleep current of 6uA with touch-to-wake. Instead of powering up the whole core to do the capacitive touch reading and averaging in the main process thread, readings are done in a zombie mode so that we only wake up when touches are detected. If your next product design needs a reliable capacitive touch interface, the CapSense 5th gen-powered Infineon PSoC™ 4000T series (https://www.digikey.com/en/products/detail/infineon-technologies/CY8CPROTO-040T/22158824) is an excellent low-power Cortex M0+ chip that can act as the main processor of your product with high integration for a tiny BOM at an attractive price. You can get started fast by picking up a CY8CPROTO-040T eval board (https://www.digikey.com/short/j5hfb704) that has a programming/debug interface as well as button, slider and proximity sensing CapSense element. Order today and your CY8CPROTO will ship immediately, so that you can get started with your development by tomorrow afternoon!

SMT DIP switches are an excellent way to add quick configurability to a design - they are more compact than individual switches, more usable than cuttable pads, and less fiddly and error-prone than pin jumper shunts (https://www.digikey.com/en/products/detail/sullins-connector-solutions/NPC02SXON-RC/2618266). For a new design, there are 4 configurable switches but we wanted to keep the board nice and compact - so using 'full sized' 2.54mm SMT DIP switches (https://www.digikey.com/en/products/detail/te-connectivity-alcoswitch-switches/1-1825059-3/1021562) would take up half the PCB. Then we saw a design with a tiny SMT switch and realized that these handy components come in a compact 1.27mm size too! Let's go find one for our breakout at DigiKey.

This week's EYE ON NPI is catchy like an 80's pop song (https://www.youtube.com/watch?v=LPn0KFlbqX8), it's ams OSRAM's TCS3530 True Color Sensor (https://www.digikey.com/en/product-highlight/a/ams/tcs3530-true-color-sensor) It is a new light sensor from ams OSRAM that is pre-calibrated for CIE XYZ color temperature sensing output, without a lot of gnarly math! We're huge fans of ams's light sensors, one of our first sensor breakouts was the TSL2561, (https://www.digikey.com/en/products/detail/ams-osram-usa-inc/TSL2561T/3095179) a wide-input-range light sensor with an I2C interface. We followed that up with a breakout for the TCS34725 which can detect separate red, green, blue and clear channels. With a little math, color reflected off of objects can be calculated into RGB color-space - we used it to make an umbrella that matches whatever color it touches! (https://learn.adafruit.com/florabrella/) Since then, ams OSRAM has worked to create better light sensors that reduce the need for end-user calibration or a lot of microcontroller lifting. The chips have carefully tuned PN diodes to not only be able to report correct color values, but ideally also have little variation from sensor-to-sensor. The TCS3530 (https://www.digikey.com/short/qwt595fh) is the latest color sensor from ams OSRAM, and it's also their newest with XYZ color output! This means you can read CIE XYZ color values out directly from the driver, which is going to be the best way to model what a human eye sees (https://en.wikipedia.org/wiki/CIE_1931_color_space) - not just an optimal concept based on 'pure' RGB photodiodes. This makes it ideal for use with cameras, monitors, printers/copiers and other devices that have humans that are looking at the colors. By detecting ambient light temperature, monitors and camera sensors can adjust their white balance to have their color gamut appear more 'natural' even in yellowish incandescent or halogen, or blueish fluorescent light. The TCS3530 (https://www.digikey.com/short/qwt595fh) does this by having 8 separate PN diodes, each tuned to a specific frequency band, to cover from about 400nm to 750nm. The diodes are normalized by the ALS engine so that you don't get over-sensitivity to green or IR. The diodes are arranged in a 4-way symmetric array to get fully balanced readings across all frequencies: there's probably some reasoning to how the layout is done to avoid signal from one diode from affecting a nearby one, something ams has decades of experience with. A modulator and flicker detection system can sense light pulses such as those from incandescent bulbs (at 120 Hz) or monitors (30 to 60 Hz) so that we can sample at the same times during the wave, or sample long enough to capture a full waveform worth of light. Interfacing is fairly simple, although there are a few things to watch out for during integration. The sensor supports both I2C and I3C (https://www.youtube.com/watch?v=hC4zkvdVag4) so it's good for legacy or modern microprocessors. Note the chip requires no greater than 1.8V power and logic, so for 3.3V systems - a shifter will be necessary. Finally - the chip has a massive number of registers to tweak the settings. So while you could write a driver, you're probably best off using ams OSRAM's TCS3502 linux C kernel driver to base your implementation if you are not just using Linux/Android directly. If you want to add precision color sensing with pre-calibrated CIE XYZ outputs to your next design, the ams OSRAM's TCS3530 True Color Sensor (https://www.digikey.com/en/product-highlight/a/ams/tcs3530-true-color-sensor) is a top choice from a world leader in light sensing. And best of all, it's in stock right now at DigiKey for immediate shipment! Order today and you will get this compact all-in-one devices shipped to your door so you can start letting your true colors shine by tomorrow afternoon.

This week's EYE ON NPI is "aces", literally! It's ACES Group’s Vertical MicroSD Card Connectors (https://www.digikey.com/en/product-highlight/a/aces-group/vertical-microsd-card-connector), a great way to increase your enclosure design flexibility, maybe even improve BOM costs by not requiring a separate PCB for mechanical stability. MicroSD cards are a great way to add gigabytes of data storage for low cost and user-serviceability: they're available at just about any store - even grocery stores! Cards are usually under $10, and DigiKey stocks a huge variety of speeds and sizes. (https://www.digikey.com/short/b43p5rzq) The ACES card sockets come in two styles. The MSDV-2008-AKA0T01 (https://www.digikey.com/short/b449j9p5) is minimal, with the smallest size but no push-push eject - instead you have to pull the card out. The MSDV-2108-BK33T (https://www.digikey.com/short/7hnwrbd1) has push-push eject so it's easier to remove cards, but the overall package is much larger. The minimal one is also less expensive, about $1 in quantity whereas the fancy one is $1.60. Both come with the promise of accessing a MicroSD card at a perpendicular angle from the PCB - a design we've never seen before in a micro SD card holder! Historically, we've only seen and used 'right angle' style like the MSD-6-A from CUI (https://www.digikey.com/en/products/detail/cui-devices/MSD-6-A/21797113) - and DigiKey stocks tons of variants of MicroSD sockets (https://www.digikey.com/short/zfn2rcm3) such as hinged, push-pull, even super-skinny (https://blog.adafruit.com/2022/07/26/the-great-search-skinny-micro-sd-card-holder-for-raspberry-pi-cowbells-thegreatsearch-digikey-adafruit/). But, this is the first and only one we've ever seen that is 'vertical' not right angle, with all pins brought out plus card detection. The design is well thought-out with through-hole contacts plus 3 extra-wide mechanical stabilizers and a flat plastic seat so that customers jamming cards in off-angle won't tear the pads off. We've already picked up some of each to make a breakout board so folks can add these to their prototype design, but you shouldn't wait on us! If you want to add these two unique microSD sockets to your design - order from DigiKey today! They have both the MSDV-2008-AKA0T01 (https://www.digikey.com/short/b449j9p5) and MSDV-2108-BK33T (https://www.digikey.com/short/7hnwrbd1) in stock right now for immediate shipment. Place your order right now and you'll be integrating the new ACES Group’s Vertical MicroSD Card Connectors (https://www.digikey.com/en/product-highlight/a/aces-group/vertical-microsd-card-connector) by tomorrow afternoon.

We designed this CH552-based QT Py to play around with this '40 cent' USB-capable chip, and it's been super fun! now the hardware is complete and assembled, its time to test it so it can go into the shop. we wrote a test sketch in Arduino (https://github.com/DeqingSun/ch55xduino) board support package to verify the GPIO are working right on the pogo bed. the test output goes to the USB serial port which is then read by a python script. to program it, we use the raspberry pi and ch552tool (https://github.com/MarsTechHAN/ch552tool), we can enumerate, test and program the final neopixel swirl in about 10 seconds.

This week, we've been spending a lot of time testing out our ESP32-C6 Feather against a variety of FeatherWings, to test all the peripherals and pin definitions. Good news, so far everything works! Some folks in the community emailed us asking about different varieties of the ESP32-C6, and whether they should go with the QFN, WROOM, or Mini modules. We'll show all the available variants at DigiKey - they've got all of them - and the pro's and con's of each type.

This week's EYE ON NPI will take you for a SPIN around the block - it's STMicroelectronics' STSPIN32G0 Three-Phase BLDC Controller (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/stspin32g0-three-phase-bldc-controller) series of chips, featuring 250 or 600 V three-phase BLDC FET controllers with integrated embedded STM32 MCU! These chips are an 'all in one' solution to advanced motor control when you want to have sensors and tight integration, or a super tiny footprint. As budding robotics hobbyists, we've designed and stocked many products - like this Motor Shield (https://www.adafruit.com/product/1438) - to support a variety of small DC motors. Some well known varieties are: Hobby Servos, DC brushed motors, and steppers. Hobby servos are actually just DC brushed motors with a feedback circuit, so we'll ignore those. DC brushed motors are simple: apply a positive DC voltage to the two wires, and the rotor spins one way. Apply a negative voltage, they spin the other way. As you can expect from the name, inside are brushes, that connect from the rotating center to the two permanent magnets on the outer diameter (https://en.wikipedia.org/wiki/Brushed_DC_electric_motor). This makes them inexpensive, and very easy to use: simply PWM the voltage to change the speed, invert the voltage to change direction. Nothing more complex than an H-bridge is required. But the brushes do eventually wear out, or oxidize, or splinter. Which means the motors will eventually 'die' and need replacement. Fine for toys and simple products that have low usage, but not appropriate for white goods or automotive or anything where life-time and reliability are essential! Stepper motors are a tad more complex: in order to have precise movement, they use a bank of 4 electromagnetic coils to 'step' the axle around a little bit at a time (https://en.wikipedia.org/wiki/Stepper_motor). No brushes to replace! But they don't rotate fast: the point is they have small accurate steps, and they're kinda expensive. What if we could combine DC brushed motors and steppers to create... Brushless DC Motors? Wow, so smart! That's exactly what a BLDC is, a DC motor that has no brushes, but does have multiple windings that have to be synchronized right to rotate. They're a little more expensive than brushed motors, but not significantly. The biggest cost increase is in the driver complexity because you need to drive and sequence three branches, whereas the commutator/brushes on a brushed motor handles that for you. Normally folks will use their favorite microcontroller, then wire it up to a BLDC driver (https://www.digikey.com/short/3bf72p89), like the L6235Q (https://www.digikey.com/en/products/detail/stmicroelectronics/L6235QTR/2772201) which can push 2.5A per-bridge at up to 52V. But, wouldn't it be nifty if you didn't have to do any wiring, so that even for small designs, you can have a fully integrated motor controller with your main microcontroller. Or, you could use the microcontroller as an I2C or SPI peripheral that integrates the temperature/current/voltage/torque monitoring that you would normally have to manage as a interrupt-run thread on a main core. That's what we've got here with the STSPIN32G0 Three-Phase BLDC Controller (https://www.digikey.com/short/977t8ftv) series of chips. It's a ARM Cortex M0 STM32G031C8 (https://www.digikey.com/en/products/detail/stmicroelectronics/STM32G031C8U6/10300273) running at 64MHz and 64K flash / 8K SRAM, with standard peripherals, debug, and even some 5V-friendly GPIO. Inside, the STM is bonded to the control circuitry so that 3 sides are used for microcontroller interfacing, and the fourth side is high-voltage friendly with separated pads. Program it just like any other STM32G031C8, and just define the motor control pins to the bonded wires. And then you'll need to connect the 6 power IGBT/FETs to create the 3 driving half-bridges such as STGD6M65DF2 (https://www.digikey.com/short/7dwq7zw2) Are you ready to have a super-integrated BLDC driver board that comes with a top-notch Cortex-M0 and all the power-driving experience ST has to offer? You're in luck because the STSPIN32G0 Three-Phase BLDC Controller (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/stspin32g0-three-phase-bldc-controller) is in stock right now at DigiKey for immediate shipment. Check out the all-in-one EVSPIN32G06Q1S1 eval board (https://www.digikey.com/en/products/detail/stmicroelectronics/EVSPIN32G06Q1S1/22470459) if you want to immediately start testing out the STSPIN32G0. Then place your order today so you can start putting your own spin on motor driving by tomorrow afternoon.
