This week's EYE ON NPI is another great step forward in Bluetooth Low Energy development, it's Nordic's new nRF54 series (https://www.digikey.com/en/product-highlight/n/nordic-semi/nrf54l15-multiprotocol-soc) and nRF54L15 Wireless SoC Development Kit (https://www.digikey.com/en/product-highlight/n/nordic-semi/nrf54l15-wireless-soc-development-kit). This is the heir-apparent to the popular nRF52840 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF52840-CKAA-R/15929796) series chip which we know and love so much. The nRF54 series comes in L and H variants, for 'low' and 'high' power, but even the L series is a step up, with Cortex M33 running at 128MHz, and up to 1.5MB ReRAM (https://en.wikipedia.org/wiki/Resistive_random-access_memory) / 256KB SRAM. The H series is a whole new ball-game with dual M33 running at 320MHz, 2MB of ReRAM and 1MB of SRAM plus upgraded peripherals. Wow, the nRF series has come such a long way from the baby-steps of the SPI-peripheral nRF8001 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF8001-R2Q32-T/4626390) to the early ARM Cortex M0 plus BLE combo chip, the nRF51 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF51822-QFAB-R7/4626396). We still use that nRF51 in many of our Bluetooth LE boards like the Feather 32u4 and M0 (https://www.digikey.com/en/products/detail/adafruit-industries-llc/2995/5823444), also as a SPI-peripheral-to-BLE converter. The next big upgrade was the nRF52832 (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF52832-QFAB-R/6051565) which bumped the processor from an M0 to an M4, but didn't do a huge bump to the Flash or SRAM compared the nRF51. The big leap after that was the nRF52840 which is still an amazing chip: USB peripheral means you can use this chip as the main processor, and it can do all your processing, user interface, sensor reading and wireless communication with only a few passives to support it. There was an nRF5340 released about two years ago (https://www.digikey.com/en/products/detail/nordic-semiconductor-asa/NRF5340-CLAA-R/14323741) but much like Windows releases, we tend to skip every other chip. We happened to check digikey.com/new yesterday and saw the nRF54L (https://www.digikey.com/short/zf8pz0cr) series pop up, which is exciting as it was pre-announced about a year ago (https://www.youtube.com/watch?v=XG8bRNaNHrg) and is now shipping to customers! The nRF54L (https://www.digikey.com/short/zf8pz0cr) comes in three variants, which is not surprising because we've seen earlier chips come in 'lite' versions that cut pricing by having less flash or RAM. All variants have a 128MHz Cortex M33 with a RISC-V co-processor, and a BLE stack. One interesting thing we noted, is that instead of flash memory, which is big and expensive and hard to do with modern fab processes, the nRF54 uses ReRAM (https://en.wikipedia.org/wiki/Resistive_random-access_memory) which is non-volatile and uses memristor technology, which is pretty cool! The nRF54 series supports BLE 6, one new capability is channel sounding (https://en.wikipedia.org/wiki/Channel_sounding) which will improve the ability of phones to locate 'find my' tags that have become such a popular usage for the nRF chipset. Traditionally, the nRF52 chips in these tags use RSSI to measure approximate distance. There's been some improvements on the technology such as Angle-of-Attack that was introduced in BLE 5.1 (https://www.youtube.com/watch?v=EosGQtGioiY) but now with a broad-sprectrum burst it's looking like some of the lessons from UWB (https://blog.adafruit.com/2024/03/15/sera-nx040-ultra-wide-band-and-bluetooth-combo-module-eyeonnpi-digikey-digikey-lairdconnect-adafruit/) are being integrated to the BLE specification to improve item location. The nRF54L series is launching with the L15 variant (https://www.digikey.com/short/rd9fr19f), that's the one with the most memory, so it's a good start: once you have your design settled you can transition to the smallest chip you can get away with. They're coming into stock shortly so sign up at DigiKey to get notified when the package you're looking for arrives. While you wait, you can order up one of the nRF54L15-DK (https://www.digikey.com/short/qvhqv85q) dev kits, which are only $39 and in stock right now for immediate shipment. Order today and you'll get everything you need to start developing the nRF54 (https://www.nordicsemi.com/Products/Development-hardware/nRF54L15-DK) - a built in debugger, power management chip, broken out GPIO, user buttons and LEDs. While you wait for your dev kit to arrive, you can start thinking about the nRF54H series (https://www.nordicsemi.com/Products/nRF54H20) which is the high-end chip with dual M33 running at 320 MHz, 1 MB of SRAM, 2MB of ReRAM , high speed USB and I3C support (https://www.youtube.com/watch?v=hC4zkvdVag4)!

We had a request to stock more stepper driver boards, and they've got a point: we have a few brushed DC driver boards based on chips like the DRV8833 (https://www.digikey.com/short/z14mb55f) but no dedicated chips like the Trinamic's (https://blog.adafruit.com/2020/06/18/eye-on-npi-tmc2226-sa-ultra-silent-stepper-motor-driver-eyeonnpi-digikey-adafruit-digikey-adafruit-trinamic_mc/). We started a design with the 'classic' A4988 (https://www.digikey.com/short/hfz0ttv5), but it's been many years since that chip was released, let's find another option that has microstepping, and can drive stepper motors at 5V.

This week's EYE ON NPI is Perfect and Looking Cool - We're checking out the Arduino Opta line of programmable PLCs (https://www.digikey.com/en/product-highlight/a/arduino/opta-expansions). PLC stands for "programmable logic controller" (https://en.wikipedia.org/wiki/Programmable_logic_controller) and these devices are used in manufacturing and robotics to automate sensor inputs and robotic control outputs in factories. Because of dependable PLC performance, your food, clothing, medicine and water are affordable and high quality, with repeatable results. Manufacturing engineers have used PLCs since the 80's, and they've been essential for the 3rd Industrial Revolution (https://en.wikipedia.org/wiki/Information_Age). If in the second industrial revolution moved us from individually-manufactured handmade goods (https://en.wikipedia.org/wiki/Handicraft) to assembly-line repeatability (https://en.wikipedia.org/wiki/Assembly_line), then the information age and PLCs took us from the back-breaking work of doing the same task day-in-day-out to robots (https://www.youtube.com/watch?v=CjL_dQ5HAAg). Tasks like: measuring out the exact weight or count of product, applying labels, heating to temperature and holding it there for 45 minutes. While designing the machines that do this automatically is also time-consuming expensive, it's something you only have to do once. The Opta was designed in collaboration with Finder, (https://opta.findernet.com/en/) an Italian company like Arduino, which specializes in PLC design. This is a great team-up because Finder already had a family automation products and tools, so it has the industrial experience whereas Arduino has the IDE, cloud and PCB-design skills to bring in the user experience. The Opta family looks like a classic PLC, with screw terminal inputs and outputs. There are LEDs embedded to the case that can be controlled, as well as analog inputs, digital IO and built in power relays. All of the IO ports have wide voltage ranges like 0-10V and are well protected from under/over-volting, short-circuiting or ESD. Inside is an STM32H747XI (https://www.digikey.com/short/hzr2rnv2), a ultra-powerful Cortex M7 @ 480MHz + Cortex M4 @ 240MHz chip with a ton of SRAM and Flash. It can easily run an entire factory! Some versions have WiFi, Ethernet, or RS-485 for connectivity - however they are all designed to run standalone. Traditional PLCs are completely opaque, to the point where you have to use only the proprietary software that the vendor provides. What's nice about the Opta (https://www.digikey.com/short/jbb74j41) is you get to use the Arduino IDE, which has integrated support with a couple different programming systems. (https://docs.arduino.cc/software/plc-ide/tutorials/plc-programming-introduction/) You can of course use the classic Arduino sketch system (https://opta.findernet.com/en/tutorial/getting-started) and use digitalWrite(), analogRead() and all the other C++ capabilities of the classic IDE. But you can also use the classic "IEC 61131-3 programming languages" (https://en.wikipedia.org/wiki/IEC_61131-3), Structured Text ST, Instruction List IL, Ladder Diagram LD, Sequential Function Chart SFC, and Function Block Diagram FBD. These are somewhat archaic languages, but many mechanical engineers are trained in their use, so the Opta is a nice transitionary device. There's also expansion options so if you want more digital input pins and relays, you can plug a port on (https://www.digikey.com/en/product-highlight/a/arduino/opta-expansions) which will give you 16 more inputs and 8 more SSR or electromechanial relay outputs. If you've ever been curious about how PLCs work, or if you want to maintain, upgrade or repair factory equiptment, the Arduino + Finder Opta (https://www.digikey.com/short/jbb74j41) is an great product which will let you replicate the microcontroller experience to industrial automation. And best of all, it's in stock right now at DigiKey! Order today and DigiKey will ship your Opta immediately so that you can be manufacturing the future by tomorrow afternoon.

Following up on our last Great Search for a DMX / XLR connector, our next step is to find a DMX transceiver. We started by looking at official and common DMX shields for Arduino since we know there's a ton out there, including the semi-official TinkerKit brand (https://web.archive.org/web/20140727121929/http://www.tinkerkit.com/dmx-master-shield/). These boards all use the MAX485 (https://www.digikey.com/short/q7mbb9bj) and XLR connectors. They often *don't* have isolation or transient voltage protection. While the MAX485 is readily available, let's look at some other options that might work out for our design, especially if they have isolation built in!

We covered a DMX transceiver on EYE ON NPI (https://www.youtube.com/watch?app=desktop&v=X12v_qLC4-M) a few weeks ago, and after learning about how DMX works, we decided to make a DMX FeatherWing much like the MIDI 'Wing (https://www.adafruit.comproduct/4740). We'll need a chip, a hardware UART, and a couple of GPIOs. We'll also need two DIN connectors, one for the input and one for the output. We're sure that we can get some simple through-hole components through DigiKey; let's look for both the "input" and "output" directions for the DMX connectors.

This week's EYE ON NPI knows where New York Hottest Club is at, it's the Teledyne FLIR Lepton® 3.1R Pocket-Sized Thermal Camera (https://www.digikey.com/en/product-highlight/t/teledyne-flir/pocket-sized-thermal-camera), a bite-sized full-featured video camera for remote thermal measurements. With a resolution of 160x120 pixels, remote temperature measurements of -40°C to +300°C, and the size of a coin, this camera can be embedded into any kind of product, whether it's running Linux, RTOS or a plain old microcontroller. Thermal cameras are multi-purpose, with usage in medical, industrial, construction, maintenance and security industries. Use them to make sure equipment is running at the right temperature and not overheating, that insulation for a room is performing adequately, locating people or animals, or detecting fevers without touching. FLIR makes the best low-cost, small-size thermal cameras and they're available off-the-shelf at DigiKey for quick integration. Each camera outputs either a simple grayscale-valued frame or one with a false-color RGB888 palette - the palette can be configured over I2C. The Lepton 3.1R is one of a series of cameras available from FLIR, including the Lepton 2 and 3.5. What's great is all have the same physical pinout and shape that can plug into a socket. This is great for manufacturing yield and field repair: the expensive module is placed last in the manufacturing line so earlier yield issues don't affect it. Also you can swap different resolution/FOV modules to customize for the end-user. For example, the Lepton 2 (https://www.digikey.com/en/products/detail/flir-lepton/500-0763-01/6250105) is a little less expensive but has only 80x60 pixels. Or you can upgrade to the Lepton 3.5 (https://www.digikey.com/en/products/detail/flir-lepton/500-0771-01/7606616) with similar resolution but a narrower FOV. Note that the FOV will affect the distortion greatly: a wider FOV requires a lens to focus the IR emissions but will fisheye the middle and compress the edges. There's software from Teledyne FLIR (https://www.flir.com/developer/lepton-integration/lepton-3.1r-dewarping-application-note/) that will "de-warp" the 3.1R's output, using Open CV, to give you more realistic imagery. To learn how to work with these modules, we recommend the Lepton engineering integration guide (https://flir.netx.net/file/asset/13333/original/attachment). Unlike the simplest thermal camera modules and sensors, which use only I2C, or the most complex USB-video output devices, the Leptons use a combination on I2C for configuration - called the CCI Command and Control Interface - and SPI for VoSPI - a.k.a. video over SPI. This makes them possible to integrate with a wide range of microcontrollers or microcomputers. As mentioned before, you don't solder the cameras to the PCB. Instead they are plugged into a common Molex 1050281001 socket (https://www.digikey.com/en/products/detail/molex/1050281001/3045223) which is only $1 at DigiKey and comes on a pick-and-place reel. If you want to get started very quickly, DigiKey and GroupGets (https://www.digikey.com/en/supplier-centers/groupgets) have partnered up to offer a wide range of breakout boards, USB adapters and dev-boards that feature the Teledyne FLIR Leptons (https://www.digikey.com/short/2djrnzpr) GroupGets also published firmware and example code (https://github.com/orgs/groupgets/repositories?type=all) to get you started with their products so you can quickly evaluate the Lepton and make sure it will work and what resolution/FOV is ideal: simply swap the different models in and out of the Molex socket. GroupGets also works with makers to get their prototypes to market, working with DigiKey for part sourcing (https://www.digikey.com/en/blog/digikey-partners-with-groupgets-to-help-startups-getmade) so if you have an idea and need a help making it to production check them out! If you need a high-quality thermal camera that is plug-and-play, easy to integrate and at a great cost, the Teledyne FLIR Lepton 3.1R Pocket-Sized Thermal Camera is hot hot HOT and in stock right now for immediate purchase from DigiKey (https://www.digikey.com/short/0zr8w59q). Order today, pick up an eval board too, and you can be measuring the world around you by tomorrow afternoon.

This week's EYE ON NPI is the ideal component for your next power supply design, it's Nexperia's NID5100 Ideal Diodes (https://www.digikey.com/en/product-highlight/n/nexperia/nid5100-ideal-diodes) a simple design improvement to Schottky diodes or simple P-FET polarity protection. This small and low-cost component from Nexperia is their first 'ideal diode', and can be used in many low voltage power supply setups to reduce power loss and get you more product life from your battery Diodes, who doesn't love them? (https://en.wikipedia.org/wiki/Diode) You put some P-doped Silicon next to N-doped Silicon (https://en.wikipedia.org/wiki/P%E2%80%93n_junction) and before you know it, you have accidentally semiconductored! Make them big enough and you can even solve global warming (https://en.wikipedia.org/wiki/Photovoltaics) We use diodes all the time, and they're particularly useful for power supplies since they make sure current only goes one way. We often use them in front of a DC jack, between the power input and the circuitry: this keep the voltage polarity positive with respect to ground, since most modern microelectronic components want between 3-24VDC. Or, as an OR: either battery or USB power are hot-swapped so that whichever gives the highest voltage will run the downstream electronics - see our Trinket M0 schematic for a simple example (https://learn.adafruit.com/adafruit-trinket-m0-circuitpython-arduino/downloads) When we first started electronics we'd use the classic 1N4001 (https://www.digikey.com/short/d8jn3f9v) - this low cost diode can handle high currents and about 1A continuous, with about 1-2V forward drop. When we did +12V power to an LM7805 (https://www.digikey.com/short/7vv3zc1d) this was fine, we have 5V to burn. Sometimes if we were feeling fancy we'd use a Schottky diode like the 1N5817 (https://www.digikey.com/short/8fntvnrv) which has about 0.7V drop, these are often used for boost or buck converters where you don't want to lose efficiency in your free-wheeling diode switch. But when using a 3.7V nominal voltage lipoly battery into a 3.3V regulator, we have to dial it down - even 0.7V is too high - so we'd often reach for a lower-drop Schottky like the Nexperia PMEG2010 (https://www.digikey.com/en/products/detail/nexperia-usa-inc/PMEG2010ER-115/2119861). We still use this part a lot, but we could do better with an Ideal Diode like the NID5100! (https://www.digikey.com/short/4td40hmh) Ideal diodes are as close as possible to the platonic ideal (https://en.wikipedia.org/wiki/Theory_of_forms#Ideal_state) of a diode as possible: Forward conduction only, with zero reverse conduction, and minimal voltage drop. Sometimes folks try to mimic this with a reversed P-FET and yes this will give minimal forward voltage drop for polarity protection (http://www.youtube.com/watch?v=IrB-FPcv1Dc), but it has 'infinite' reverse leakage instead of close-to-zero. The NID5100 is more complex, with additional circuitry for driving the P-FET. It can be used either as a polarity protection for a DC or battery input where there's risk of the voltage being inverted, or as an OR-ing voltage select. Compared to a Schottky, it can handle 1.5A continuous - most basic Schottky's are 1A - and with a forward voltage drop of only 50mV at 0.1A. The package size and price is also very comparable to a SOT323 diode, in an easy-to-place TSSOP6 and under 10 cents in reel quantity. We also like the extra pins like an Enable, so it can also act as an on/off switch, and a Status pin that lets you know when the diode is conducting: this can be used to detect which power supply is active in an OR setup. Does the Nexperia NID5100 (https://www.digikey.com/short/4td40hmh) sound like the ideal solution to reduce heat and power loss in your next product? Yes! And it's in stock right now at DigiKey for immediate shipment. Order today and you'll receive your components faster than a diode switching time, for integration into your BOM by tomorrow afternoon.

We're working on the LPS28 (https://www.digikey.com/en/products/detail/stmicroelectronics/LPS28DFWTR/15903340) sensor this week. This is a 'ported' pressure sensor—you can connect a tube to it so you can measure pressure somewhere else (https://learn.adafruit.com/st-lps33-and-circuitpython-sip-and-puff). But you need the tube! Folks always ask us how to find matching tubing. Let's look at what is available and how you can connect to a pressure sensor port.
