This week's EYE ON NPI is super phat not unlike a pair of ultra wide JNCOs (https://jnco.com/collections/womens-1/products/the-camilla-jeans-27-vintage-houndstooth) it's the Laird Sera NX040 Ultra-Wide Band and Bluetooth Combo Module (https://www.digikey.com/en/product-highlight/l/laird-embedded-wireless-solutions/sera-nx040-ultra-wide-band-and-bluetooth-combo-module), a compact solution that combines the best of NXP UWB and Nordic BTLE into a single easy-to-use module that is ready for instant integration into your location-based identification products or projects. We often get folks asking how they can do indoor location projects: where an object is tracked in a 2D or 3D space, with high precision. For outdoor projects, most people use GPS/GNSS (https://en.wikipedia.org/wiki/Satellite_navigation) which can give 10 meter accuracy anywhere in the world. Or, sometimes people use cell tower triangulation (https://blues.com/blog/use-cell-tower-and-wi-fi-triangulation-to-achieve-pin-point-locations-without-gps/) to give rough estimates of location world-wide. However, both of these require you to be outside, with either network connectivity or a GNSS fix - and like we mentioned, you can't get better than 10 meter accuracy without very expensive RTK modules (https://blog.adafruit.com/?s=eye+on+npi+rtk). Indoors, sometimes its possible to use WiFi time-of-flight, or BTLE ToF / AoA (https://blog.adafruit.com/2021/08/19/eye-on-npi-xplr-aoa-direction-finding-and-indoor-positioning-explorer-kit-eyeonnpi-digikey-ublox-digikey-adafruit/) More interesting, we can also use multiple stationary transmitters to determine the 3D location of a mobile device. Instead of looking for one pulse, we encode the transmitter ID into the pulses, and then can correlate each received pulse to the fixed 3D location of the station. As long as we have 4 stations, we can solve for XYZ and yes that's a lot of stations but you can get 10cm accuracy, which blows away BTLE and WiFi RSSI or ToF methods. Note that doing the triangulation on UWB pings requires a ton of math which is why having a ready-to-go module is great because NXP and Laird will provide example code to get you started. While most folks think of UWB as a 3D locator, NXP promotes some other use cases - most notably peer-to-peer payments (https://www.nxp.com/company/about-nxp/nxp-collaborates-with-ing-and-samsung-to-pilot-industrys-first-uwb-based-peer-to-peer-payment-application:NW-NXP-COLLABORATES-WITH-ING-AND-SAMSUNG-TO) and keyless car access. The key-less entry proffer is the most timely as there's been a spate of car theft rings that use relay attacks to amplify the signal from a key fob (https://www.nytimes.com/2015/04/16/style/keeping-your-car-safe-from-electronic-thieves.html) if the car is parked close to the house and the keys are kept near the door. Thanks to UWB now being included in iPhones and in the iOS API,you can likely have customers use their iPhones to directly interact with the Sera NX040. To save you time and integration costs, the Sera NX040 (https://www.digikey.com/short/hmzt8whq) include the NXP UWB chipset and all supporting circuitry, plus a Nordic nRF52833 (https://www.digikey.com/short/jj9r27p2) which is a Cortex M4 with all the peripherals, plus the best Bluetooth LE radio on the market. Nordic's chips are especially good at low-power use-cases so battery-powered designs will benefit from this combo. The NXP SR040 is wired to the nRF via SPI - you'll use the NXP SDK for that, which you need to contact NXP for. Or you can use the Laird MicroPython build which comes with some ready-to-go examples. The Seras are available with either built in tuned antenna (https://www.digikey.com/short/hmzt8whq) or a external antenna connection - you'll need to pick up a NanoUWB antenna (https://www.digikey.com/short/1wq0t5r0) to match (https://www.digikey.com/short/ctw5m4t8). As you can expect for a device with two wireless components, proper layout is essential to get good performance from both the BLE side and the UWB side - check the Laird documentation on how to set up keep-outs and ground planes. Finally, if you want to get started you can always pick up the NX040 Eval Board (https://www.digikey.com/short/hhtqhwc9) which has SWD debug for programming the nRF, USB connection for MicroPython or Zephyr debugging, and a separate RP2040+MikroBus+Qwiic half that can be used for adding sensors or displays. Whew, this NPI was not just ultra-wide but ultra-long: we learned a lot while researching the Sera NX040 (https://www.youtube.com/watch?v=KWf9fcx26wg) and the modern uses of UWB! If you want to get in on this multi-purpose RF protocol, you're in luck because DigiKey has the Laird Sera NX040 UWB+BTLE Module (https://www.digikey.com/short/hmzt8whq) and accessories in stock right now for immediate shipment. Order today and they'll send you parts faster than an UWB pulse so you can get started with integration in nanoseconds.

This week's EYE ON NPI will galvanize your next design, with robust galvanic isolation specifically for I2C devices: we're highlighting the Analog Devices ADuM1252/3 Bidirectional I²C Isolators (https://www.digikey.com/en/product-highlight/a/analog-devices/adum1252-bidirectional-i2c-isolator). They are available in two flavors: as the unidirectional ADuM1253 (https://www.digikey.com/short/0w8fq3w5) and bi-directional ADuM1252 (https://www.digikey.com/short/r4j3tcrf). These little SOIC chips provide trustworthy isolation up to a shocking ±10 kV surge, with pending safety and regulatory approvals, so you can feel confident that your design is created as safe as possible. Digital isolation (https://www.analog.com/en/product-category/isolation.html) is essential when dealing with medical, industrial or robotic designs. For industrial/robotic applications, the motors are very noisy and you want to make sure that there is no direct path for that electrical noise to your delicate sensors or microcontrollers. With medical cases, engineers are often tasked with measuring very fine sensors, with uV signals, and providing repeatable data that is used for life-or-death decisions, while also making sure that the 'DUT' is never exposed to dangerous voltages all in an environment with tons of other equipment, some of which may be misbehaving...that's a lot of pressure! The ADuM1252/3 is specifically designed for isolation of I2C signals: you can't just use 'any' isolator because I2C is a bi-directional data protocol that uses pull-ups on open-drain data and clock lines to communicate from controller and peripheral. The ADuM1252 (https://www.digikey.com/short/r4j3tcrf) has bi-directionality on both SDA and SCL, useful for 'multi-controller' modes or when clock stretching is used. The ADuM1253 (https://www.digikey.com/short/0w8fq3w5) has unidirectional SCL for most common I2C devices, and is a little less expensive. The ADI iCoupler technology uses 'galvanic' isolation, that's not the same as optoisolation! According to ADI, you'll get much better data-rate performance and isolation with galvanic compared to optoisolation. Also, lower power since you don't have to turn on/off an LED. Plus you can also use iCoupler for power transfer, which optoisolation cannot do. (https://www.analog.com/media/en/technical-documentation/frequently-asked-questions/icoupler_faq.pdf) The way iCoupler works is by creating a tiny transformer (https://en.wikipedia.org/wiki/Transformer) with two sets of metal coils, separated by an isolating polyamide layer. For data transfer, little coils are used and for power transfer, bigger coils can handle a couple mA! Of course, if we're using a transformer, you know that DC signals cannot be passed through, only AC; and data has a DC component plus isn't a sine wave. That means that there's also a data-to-AC codec on board that will turn I2C signals to AC, then back to I2C. All this is managed transparently so you don't have to worry about it, just treat it as a single I2C bus. There's also a couple nice extras that are helpful if you're trying to make I2C more fault-tolerant. Pre-charge circuitry and 'stuck' detection allow hot-swapping, either purposeful or accidental. The two isolated sides are not connected together until the Side2 half is in a neutral-bus condition. Since each side is separate, you can also use the ADuM1252/3 (https://www.digikey.com/short/1vbn4hcb) for level shifting: either half can be between 1.7 and 5.5V power and logic. With the fast iCoupler codec, you can get up to 2 MHz clock rate for fast I2C data transfer. If you need iCouplers for other protocols like USB or SPI - Analog devices has those available as well, each version is tuned for the usage so you get the best performance. If you need high performance galvanic isolation for your next I2C design, the Analog Devices ADuM1252/3 Bidirectional I²C Isolators (https://www.digikey.com/en/product-highlight/a/analog-devices/adum1252-bidirectional-i2c-isolator) will do an excellent job at creating a code-transparent galvanic barrier for up to 2 MHz bidirectional I2C communication. And best of all, both the unidirectional ADuM1253 (https://www.digikey.com/short/0w8fq3w5) and bidirectional ADuM1252 (https://www.digikey.com/short/r4j3tcrf) are stock at DigiKey right now for immediate shipment. Order today and you'll be gallivanting your way to iCoupler bliss by tomorrow afternoon. See the ADI video https://www.youtube.com/watch?v=4cH-ym9QJlQ

This week's EYE ON NPI is virtually the best chip you could get for VR tracking - it's the TS4631 Light-to-Digital Converter (https://www.digikey.com/en/product-highlight/t/triad-semiconductor/ts4631-light-to-digital-converter) a specialized mixed-signal ASIC that is designed especially for folks who want to design accessories for the SteamVR (https://store.steampowered.com/app/250820/SteamVR/) and specifically, HTC Vive hardware (https://www.vive.com/us/). Thankfully, this chip is available without restriction or NDA, which means it's theoretically possible for anyone to design tracking technology without the hard part of making the fixed-base-transmitters. Precision 3D tracking within a room is incredibly hard: Cameras can kinda do depth perception but they require a lot of computation and often make mistakes on object recognition. You can try using UWB but it's very pricey and has precision limitations. HTC Vive solves this by using IR light, which is not-sensitive to room illumination, doesn't have RF interference, and is fairly inexpensive. Each 'lighthouse' acts like a lighthouse: after an initial Infrared burst for sync, it sweeps IR over X & Y directions. Check out Alan Yates' detailed talk for how this design works (https://www.youtube.com/watch?v=75ZytcYANTA) The object being tracked has an IR photodiode, which catches the sync pulse, then measures the time between that and the X and Y sweeps. It does this for each lighthouse. With some fun matrix math (https://trmm.net/Lighthouse/), it can then calculate it's X Y Z coordinates with respect to the Lighthouses and, given we know the location of those Lighthouses during an initial calibration step, we can localize that IR diode within the fixed coordinates of the room we're in. That means that if you want a device that can detect the IR pulses and sweeps, all you need is an IR photodiode like the OSRAM BPW 34 (https://www.digikey.com/short/b5jn4pnp) and a bunch of analog electronics to filter out ambient noise, detect the carrier frequency, and give you the timing pulses detected. Or, you can save yourself a ton of effort, and just go with the Triad TS4631 (https://www.digikey.com/short/fwr173wh). All you need is the photodiode and a couple simple passives and you can have a configurable sensor analog front end at low cost and low complexity. In fact, that's what nearly all Vive-compatible hardware uses. (https://twitter.com/SadlyItsBradley/status/1634146181755355136) The Triad TS4631 (https://www.digikey.com/short/fwr173wh) comes in a compact 0.4mm-pitch 9-pin BGA package, which thankfully uses the center ball as a second ground so no buried vias are required. Give it 3.3V power, a BPW 34 S (https://www.digikey.com/short/p8j9r7z0) photodiode, and a couple passives for the power supply, and it's ready to go! There's two output pins for the Envelope and Data from the IR signal. Those two pins are also the I2C configuration pins, and you can use any microcontroller to read and write the configuration registers that let you set up the gain, thresholds and sleep modes. There's a library for the TS4231 (https://github.com/TriadSemi/TS4231) available from Triad, and since the TS4631 mostly improves the TS4231's power usage, you can likely start your microcontroller interfacing and development with that code. There's also lots of other folks playing around with the Triad TS4631 (https://www.digikey.com/short/fwr173wh) and TS4231 (https://www.digikey.com/short/fmcj4wft) which means that you can find hobbyist projects for design inspiration. We found some great info from famed hackers CNLohr (https://hackaday.io/project/153224-ts4231-esp8266-lighthouse-tracking) including libsurvive for desktop tracking (https://github.com/cntools/libsurvive/), Trammell Hudson (https://trmm.net/Lighthouse/), and other YouTube makers (https://www.youtube.com/results?search_query=ts4231). There's also a published project called HiveTracker (https://hivetracker.github.io/) that has hardware and firmware for a fully-designed tracker board with Bluetooth LE as the backchannel. If you want to get started with making 3D-trackable devices for VR or AR applications, it's great to not have to build the whole system from scratch. With the Triad TS4631, (https://www.digikey.com/short/fwr173wh) you can integrate into the existing SteamVR/HTC Vive ecosystem or you can chart your own path with their hardware and your own software. Either way, you'll want to pick up some TS4631's and you're in luck because DigiKey has them in stock right now, for immediate shipment! Order today and you can be tracking in cyberspace by tomorrow afternoon.

This week we worked on some Picowbell designs, including a prototyping plate that includes a battery charger. We recycled charging and switch-over designs from our Feathers but then we realized we never showed off the charger chip itself! We tend to use the MCP73831, but there's approximately 4902 different variants! Let's take a look at how to select a charger that matches your battery: voltage and charge rate are the biggest things to check. There's also other extras like LED indicators, time-outs, and load-sharing/prioritization.

This week's EYE ON NPI is gonna give it to up high...then down low (https://en.wikipedia.org/wiki/High_five) ...ready to measure, never too slow! It's STMicroelectronics' TSC1641 Digital Power Monitor (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/tsc1641-digital-power-monitor), a high-precision temperature, voltage, power, and temperature monitoring chip with I2C or I3C interfaces for integration with modern microcontrollers and microcomputers. This chip is great for tracking actual power usage into motors, LEDs, batteries etc. to detect anomalies or conserve power, with a tiny footprint and flexible usage. The TSC1641 is a modern take on the old-shunt-resistor-into-an-opamp method of power monitoring (https://learn.adafruit.com/portable-solar-charging-tracker/analog-stuff). For one, the TSC1641 can handle high or low-side measurements. That means you don't run the risk of having your grounds floating above earth, or managing multiple reference voltages. Also of course wiring is a snap, you just insert the board in between the power rail and load. Second, it can read up to 60VDC voltages - great for big battery packs, automotive or robotics. Third, it will calculate power and low-pass filter for you so you aren't affected by spiky power usage. Fourth, there's an onboard temperature sensor tossed in. Finally, this chip is not just I2C compatible, it has I3C support https://en.wikipedia.org/wiki/I3C_(bus) which makes it a great investment for long-term designs as I3C catches on and is supported in the next generations of microcontrollers. We covered I3C in a previous EYE ON NPI (https://blog.adafruit.com/2022/05/12/eye-on-npi-nxp-p3s0200gm-i3c-switch-with-hardware-select-and-enable-eyeonnpi-nxp-digikey/) so check it out for more details. To sum up fast: I3C is back-compatible with I2C but has push-pull logic support for up-to-12MHz speeds, in-channel interrupts so a separate IRQ line is not needed, and dynamic addressing so there's no address collision. A great update to all the things that make us batty about I2C. Support for I3C on the controller-side is still rolling out so you probably will use this chip in I2C mode for now, but your firmware can be adjusted-up to I3C on a future revision. This chip is a great response to the INA series from TI - and we love competition, it's great for all engineers when the chip companies clamor for our business by iterating and improving! Compared to the INA237, the ST TSC1641 (https://www.digikey.com/en/products/detail/stmicroelectronics/TSC1641IQT/21725159) has the same specs but is 10% less, plus you get that I3C support that none of the INA chips have yet. The high level of integration means you only need to spec a shunt resistor. The resistor selection will have to balance the dynamic current range measurable with the 16-bit precision. If you pick too small of a resistor, you'll max out the measurable current faster. If you pick too large of a resistor, you wont get good accuracy at low currents. Check the datasheet for how to select a good resistor and then how to tell the chip what value you've chosen: that will let the TSC1641 perform the power/current/voltage calculations on its own without you having to do any math. If you'd like to get started fast, there's also an eval board that is Arduino-shield-compatible (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/steval-digafev1-evaluation-board-for-the-tsc1641), some firmware is provided for the Nucleo series of ST dev boards to evaluate without any soldering or coding. If you're interested in the STMicroelectronics TSC1641 Digital Power Monitor (https://www.digikey.com/en/products/detail/stmicroelectronics/TSC1641IQT/21725159) you are in luck because it's in stock right now at DigiKey! Order today and it will ship faster than you can give a high-five, and be at your doorstep tomorrow afternoon for your power-monitoring pleasure.

This Great Search is a big throwback to every electrical engineer's first power supply. The LM7805 is a mainstay regulator, available in TO-220 package, as well as TO-92 and SMT. Today, we found a social media post of someone repairing a SEGA Master System (https://twitter.com/nosIndulgences/status/1758586503868080259) where they needed to replace the LDO. Let's look for a drop-in replacement with 1A or more of current. Also, maybe we'll peek at some alternative products that can provide more current output or lower drop-out.

OK so UPDI actually stands for Unified Program and Debug Interface (https://onlinedocs.microchip.com/pr/GUID-DDB0017E-84E3-4E77-AAE9-7AC4290E5E8B-en-US-4/index.html?GUID-9B349315-2842-4189-B88C-49F4E1055D7F) but this board is so smol and kute that i will call it the Unusually Playful Device Interfacer and pat it's head when it does a good job. it's designed to make programming modern ATtiny chips very easy because it has 3 or 5V power&logic select, power and transmit indicator LEDs, and a quick cable for poking into a breadboard.

OK, well, maybe we chocolate-fudged that reference a bit but it's still a perfect day for lovers of reliable products from Hirose as today we're looking at the Hirose DF40F and friends (https://www.digikey.com/en/product-highlight/h/hirose/df40f-series-board-to-board-connectors) - diamond-rock solid connectors that mate together perfectly like perfect partners. Ok, I know your number one question, it's how to pronounce Hirose (https://www.youtube.com/watch?v=v4wd9qEZV5A) - is it "high rose"? We got ya, it's "hero say"! And they are definitely heroes when it comes to designing connectors, with well-thought-out components that you probably use all the time. For example, did you know that the ultra-popular u.FL connector (https://www.digikey.com/en/product-highlight/h/hirose/ufl-series) used almost in every RF product is from Hirose (https://en.wikipedia.org/wiki/Hirose_U.FL), patented by them in 1993 (https://patents.google.com/patent/US5180315)? Hirose DF40 connectors have popped up in many developer boards, due to their high density and ease-of-use. The first time we saw them was on the Intel Edison boards (https://en.wikipedia.org/wiki/Intel_Edison), which featured a 70-pin DF40 (https://www.adafruit.com/product/2227) for high speed USB or SDIO interfaces. More recently, the same DF40 family is seen on the popular Raspberry Pi Compute Module 4 (https://www.digikey.com/en/products/detail/raspberry-pi/SC0696/13530919), as dual 100 pin connectors that pass USB, Ethernet, PCIe, eMMC, DVI, DSI and CSI MIPI, and DPI parallel TFT displays. You can check out Shawn Hymel's guide on making an adapter board for the CM4 if you want tips on laying out and soldering DF40's (https://www.digikey.com/en/maker/projects/creating-a-raspberry-pi-compute-module-4-cm4-carrier-board-in-kicad/7812da347e5e409aa28d59ea2aaea490) And looking at the specs for the DF40 series (https://www.hirose.com/product/series/DF40) we see that these connectors are very well 'rounded': they can handle high voltages like 30V AC or DC, high speeds up to 10 Gbps, and fairly high currents 0.3A per pin - just double or triple up pins if you need more current capacity. That means you don't need separate power connectors and can power single board linux computers like the CM4 directly over the same connectors that pass HDMI and PCIe data for reliable and compact connectivity. Compared to 2.54mm or 2mm pitch headers, you don't have to worry about pins getting bent or the high offset height from IDC connectors because the Hirose DF40 series can be as low as 2mm, or as high as 4mm if you need height for component clearance. They're good for at least 30 mating cycles, with grooves to help align for easy mate and de-mate, just make sure to press down flat in the center and lift from two opposite edges so you minimize torque. If you have a submodule or multi-stacked board design and you need a low-profile, high-speed and high-power connector, the Hirose DF40F series of board-to-board connectors (https://www.digikey.com/short/dnr4r5j1) is trusted and reliable by many. I think of Hirose as the "YKK Zippers" of connectors (https://ykkamericas.com/products/zippers/): if you design a $100 board and it fails because of a poorly crafted $1 connector, the quality and reputation of your product is damaged - but if you use a reliable, enjoyable connector that makes good contact each time, the quality and reputation is enhanced! You can order DF40 and DF40F series in a wide series of sizes and configurations from DigiKey (https://www.digikey.com/short/dt70d4t0) all in stock right now and available for immediate shipment, like FTD (https://www.ftd.com/). Book today and your favorite Hirose connectors will ship instantly so that you can get to stacking and snapping by tomorrow afternoon.

we're often working with 'true analog' LED strips (https://www.adafruit.com/search?q=analog+LED), that have 1-3 channels of RGB or White LEDs. and controlling these takes a bit of wiring since they almost always need 12VDC and driver FETs. to make our lives easier, and maybe even some customer's too, here's a STEMMA board (https://www.adafruit.com/product/3893) that can convert a NeoPixel signal using a WS2811F to three AO3406 N-channel FETs (https://www.digikey.com/short/438tn2hb) that are high efficiency and can sink a chunk of current. there's a 3-channel 74LVC3G14 (https://www.digikey.com/short/tqq3tm3m) inverter in between to convert the WS2811 output signal which is open drain, to the NFETs. 5 terminal block ports allow for easy wiring of the +12V, ground, and RGB common-anode channels. unfortunately the WS2811 does not support 4-channel so this won't work for RGBW strips...but there's a lot of times folks need 1 or 3 channels!

In order to archive double-sided floppies, or deal with Apple Disk ][ drives, we need to create 'fake' index pulses, that's something that lets the software know when the disk surface has rotated 1 time. We have a guide page showing how we support 'hacked' disks using an external optical sensor (https://learn.adafruit.com/flippy-floppy-drive-modification/) but it requires some fiddly wiring. Ideally we could make a little breakout board for the reflective sensor that has a cable for quick installation. We'll want it to be 'right angle', ideally SMT solderable, and it should be a plain logic or analog type output since I2C isn't going to be fast enough to catch transitions.
