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.

This week we saw a lot of chatter about Zilog's End-of-Life Notification (https://mm.digikey.com/Volume0/opasdata/d220001/medias/docus/5570/PCN_ZAC24-0029.pdf) for their Z84C series chips. These chips were pretty cool because they were true Z80 processors and available in DIP format! They are still in stock at DigiKey for now (https://www.digikey.com/en/products/detail/zilog/Z84C0010PEG/929206) and there's a last-time-buy, so if you happen to want some large quantity, it's possible to put in a request for one last batch. There are also other Z80 processors available, so you're not totally out of luck if you need some 8-bit goodness. In theory, you could even wire-wrap or breadboard using a QFP-to-DIP adapter plate.

ATMakers emailed and asked if we'd make a Trinkey (https://www.adafruit.com/search?q=trinkey) with a TRRS jack (https://www.adafruit.com/product/5764) on the end, for making customizable HID devices that use simple 3.5mm audio jack connectors. ideally something that will make AT - Accessibility Technology - projects EZ to build and maintain. here's our take on it, what's interesting is each pin of the jack - including the two switches for tip and ring1 - connect to GPIO / analog inputs on the SAMD21. there's no pre-defined VCC or GND because different switch and joystick makers have different configurations and we might want to change around what pins are power, ground, pullups, etc! this board will be great for use with CircuitPython to make any sort of AT switch or potentiometer interface super fast, to demo it we've written up a quick CPy sketch that will listen for two switches, and when they're pressed, blink the NeoPixel and emit keypresses as if its a keyboard. code is in the PR for this board (https://github.com/adafruit/circuitpython/pull/9190#issuecomment-2067764251) since we have great HID support it could also be a mouse or joystick device and it will work with any computer/tablet/console with a USB port.

Psst...this week's EYE ON NPI is no secret, and despite having the word "Pseudo" in the name, it's the Real Deal: This week it's ISSI's Serial and Quad PSRAM chips (https://www.digikey.com/en/product-highlight/i/issi/serial-ram-and-quad-ram-solutions), an excellent addition to your next microcontroller board to quickly boost your RAM stack to megabyte proportions! Microcontrollers have come a long way since 8-bit chips like the ATmega328 (https://www.adafruit.com/product/123). What used to be a luxurious 32 KB of flash memory and 2 KB of SRAM is now nowhere-near-enough storage for handling the big computation requirements we're trying to squeeze into embedded products. It used to be enough to handle some buttons, blink a few LEDs, maybe at best read a sensor and control a motor. Now we need internet connectivity, full graphics support, and machine learning algorithms running on large sensor data sets! As we've seen, microcontrollers have evolved from 8-bit AVR to Cortex M0 to Cortex M4 and even M7 - or if you're a fan of Espressif chips, Tensilica/RISC-V 240 MHz processors. But what you are paying for in a microcontroller is often related to the density and size of the die, and on many processors, the RAM and FLASH can start to take up a dominant amount of die real-estate. SRAM and Flash may also require larger nm 'processes' that are harder to book. As a result, we're seeing chips like the RP2040 (https://www.digikey.com/en/products/detail/raspberry-pi/SC0914-13/14306010) that have on-chip SRAM but no longer have on-chip Flash memory. Instead, you're expected to pick up a QSPI flash chip and wire it up to the 6-pin interface. By clever usage of on-chip instruction cache, you can get close to on-board FLASH speeds but with the flexibility and size of external memory: it's hard to find a chip with more than 1 MB of internal FLASH but you can easily get 16 MB of external memory like the ISSI IS25WP128 (https://www.digikey.com/en/products/detail/issi-integrated-silicon-solution-inc/IS25WP128-JBLE/5431600) for only a couple bucks! OK now you've got plenty of space for your code, but what about RAM? That's where you'll be buffering graphics, storing data to process, or for IoT products, storing large packets of data that may need to be encrypted before sending/receiving. SRAM is also big and kinda expensive, so it's no surprise that many advanced processors these days also support external RAM chips. Now, most folks aware that microprocessors (as opposed to microcontrollers) have required external RAM for quite a long time - but often those used large DRAM chips with 8, 16 or 32-bit parallel interfaces like the IS42 series (https://www.digikey.com/en/products/detail/issi-integrated-silicon-solution-inc/IS42S16400J-7TL/2708623). These of course are not going to work when you only have 32-ish GPIO available. That's where 8-pin PSRAM chips come in - and we're starting to see lots of 'low pin count' microcontrollers support these. For example the iMX RT1062 (https://www.digikey.com/short/0fhbdwv0) used in the Teensy 4.1 (https://www.adafruit.com/product/4622) supports PSRAM - check the SOIC-8 footprint on the bottom. Likewise the ESP32 series has wide support for PSRAM, their modules come with 8-SOIC 2MB chips very often. The extra PSRAM comes in handy when doing large IoT projects where you have to buffer an entire image, or JSON structure. Especially over TLS connections that require a lot of RAM to process! Note that while you could use the ISSI PSRAM chips with any processor, thanks to the generic SPI or QSPI interface, you really do want a chip to have 'native' PSRAM support so that the compiler and core will automatically map the PSRAM out so it is accessed transparently to your code. You'll likely need to enable PSRAM support in your toolchain and of course wire it up to the supported QSPI interface pins. Also, sometimes you need to be careful about where some memory goes, like volatile or interrupt-accessed addresses. Sometimes you also have to tell the compiler what ID code or command-set to use, since things like enabling the QEN bit can vary from chip to chip. With a universal pinout and speedy 100MHz clock rate, PSRAM is a fast and easy way to make your micro roomier. If you're not sure which to pick, maybe start with the IS66WVS2M8BLL (https://www.digikey.com/short/29b1dzqf) a 2 MByte / 16 MBit 3.3V-logic SOIC-8 PSRAM chip. If you're ready to add encyclopedic memory in your next design, you are in luck, because the ISSI Serial and Quad PSRAM chips (https://www.digikey.com/en/product-highlight/i/issi/serial-ram-and-quad-ram-solutions) are in stock right now for immediate shipment! Order today and you'll get your chips in hand by tomorrow afternoon.

This week on the Great Search, we saw someone on social media talking about repairing an old device that has a 'split' supply with multiple voltages. (https://twitter.com/dorksince93/status/1779346977861615666) Usually your AC-DC adapter converts 110~220VAC into 12VDC. But sometimes you need +12V, -12V, plus maybe a 5V for good measure. And sometimes the connector ends up being a DIN because it has to support so many different voltages! (https://twitter.com/dorksince93/status/1779346977861615666/photo/1) Let's show how we can find this kind of device, as well as a matching cord (https://www.digikey.com/short/n8z3h7nn) on DigiKey so that we can resuscitate some old devices and keep them out of the landfill!
