While developing boards, there are oftentimes we want to program ESP chips without going through the onboard USB port; this adapter will help us (and others) do that! It has a CP2102N USB-serial chip (https://www.digikey.com/short/bm7n3p5z) with RX/TX signal LEDs and two transistors wired up to the DTR/RTS line for the 'esptool standard' reset procedure technique. The output IO, plus a 3.3V 500mA regulated output, is available on a socket header, so you can plug wires in for quick programming and debugging. You can use this for everything from an ESP8266 up to the ESP32-P4! Here, we are testing it with a HUZZAH ESP8266 breakout board (https://www.adafruit.com/product/2471), one of our first Espressif chipset products.

EYE ON NPI - Texas Instruments SimpleLink Wi-Fi CC33xx Family 12:24

17 hours پیش12:24

12:24

This week's EYE ON NPI is a super connector - it's the Texas Instruments SimpleLink Wi-Fi CC33xx Family (https://www.digikey.com/en/product-highlight/t/texas-instruments/simplelink-wi-fi-cc33xx-family) with 2.4GHz and 5GHz WiFi 6 support, plus optional Bluetooth LE, in a low cost co-processor you can add to any microcontroller project you have to instantly IoT-ify it. This family of chips is a big upgrade in the CC3 family, and looks like a very competitive solution to existing market chips - we're excited to see how TI has adapted to the existing market to bring this compelling offering. Oh the TI CC3x series, how you've grown! We first met you back when it was the CC3000, a radical WiFi co-processor with the (at-the-time) astonishing price of ~$10 per module. At the time, we crafted an Arduino-compatible shield and a breakout board (https://learn.adafruit.com/adafruit-cc3000-wifi/overview) as well as an Arduino port of the TCP/IP mini-stack so that folks could do amazing things like get the time (https://learn.adafruit.com/adafruit-cc3000-wifi/internettime), read a web page (https://learn.adafruit.com/adafruit-cc3000-wifi/webclient) or even send a Tweet (https://learn.adafruit.com/adafruit-cc3000-wifi/sendtweet). The big thing was making it so you weren't spending the $50 it cost up-till-then to add a full-linux-system-as-peripheral (https://www.adafruit.com/product/1498). Since then, TI has released some updated versions, such as the CC3100 (https://www.digikey.com/short/9cp431pr), which added 802.11n and lower power draw - we saw it featured in a few micropython projects (https://blog.adafruit.com/2016/08/24/micropython-name-badge-from-emf-2016/) thanks to the core driver support (https://github.com/micropython/micropython/tree/master/drivers/cc3100). And after that, the CC3200 series (https://www.digikey.com/short/9289jcq3), which added TLS/SSL support and had an internal ARM Cortex-M4 that could run code on its own, like MicroPython! (https://github.com/micropython/micropython/blob/master/ports/cc3200/README.md) So it's no surprise that TI is continuing to press their WiFi family forward, to now the CC33xx! The new Texas Instruments SimpleLink Wi-Fi CC33xx Family (https://www.digikey.com/en/product-highlight/t/texas-instruments/simplelink-wi-fi-cc33xx-family) comes with 4 variants: the CC330x have 2.4GHz WiFi only, where-as the CC335x add 5GHz for an additional cost. Likewise, the CC33x0 have only WiFi, and the CC33x1 have WiFi+BLE. Since all the chips / modules are pin-compatible, you can develop with one and then change in production to whatever final setup suits your product. Like the earlier chips, these chips are expected to be connected to a main processor: either a microcontroller or microcomputer, over SPI or SDIO. SPI will work great for your smaller micros, SDIO is great when you have the speed and bandwidth to shift a lot more data around. When connecting over BLE, use the UART-with-flow control - that's the standard for a "BTLE Host Controller Interface" communications (https://www.bluetooth.com/wp-content/uploads/Files/Specification/HTML/Core-60/out/en/host-controller-interface/uart-transport-layer.html). Of course, there's no way you'll want to write a driver for this kind of complex chip - so visit the CC33xx software download page (https://www.ti.com/tool/CC33XX-SOFTWARE) which has software in the form of Linux kernel patch/drivers for beefy chips, or an microcontroller with an RTOS - follow their porting guide to get it running on a non-TI chipset (https://dev.ti.com/tirex/explore/node?node=A__AEIJm0rwIeU.2P1OBWwlaA__CC33XX-RTOS-MCU__dzPVh4K__LATEST) Now you're probably saying "OK cool but I don't want to do a bunch of RF layout, I want a nice tinned module i can slap down and connect my RP-SMA or chip antenna" - and not surprisingly, it looks like there's a CC3301 module (https://www.ti.com/product/CC3301MOD) in pre-production with an optimistic budgetary price of $2.88 - that's for 2.4GHz + BLE. For the 5GHz CC3351MOD (https://www.ti.com/product/CC3351MOD) the price is $3.50. Sans BLE the CC3350MOD (https://www.ti.com/product/CC3350MOD) is $3.13. If you want a peek at what the CC3301 module might look like, the BoosterPack product page has a tantalizing glimpse (https://www.ti.com/tool/BP-CC3301MOD). You can sign up at TI's site for updates on the release schedule, or chat with your DigiKey sales rep and they'll let you know when the part makes it into general distribution. Until then, you can get plenty of TI CC3350 (https://www.digikey.com/short/3z7tqtrp) and CC3351 (https://www.digikey.com/short/hmqzwv5j) bare chips: they're both in stock at DigiKey for immediate shipment! Order today and you'll quickly add low-cost WiFi 6 + BLE support to your next design, with 2.4/5 GHz support so you're ready for any customer or configuration. With ready-to-go software, and great low prices, you can get your design set up with cutting-edge networking without breaking the BOM bank.…

The Great Search – UV LEDs for Costuming 10:23

۵ روز پیش10:23

10:23

We recently got a request to make LED sequins with bright UV LEDs for costuming projects using UV-reactive paints and textiles. Also known as 'blacklight' paint or fabric, these dyes glow fluorescent when exposed to UV light. 🔗 https://www.digikey.com/short/bndtdnbr 🔗 https://www.adafruit.com/search?q=led+sequin 🔗 https://en.wikipedia.org/wiki/Ultraviolet However, not all UV LEDs will work! UV ranges from 100nm to 450nm, and some frequencies are used for curing or disinfection. For light effects, 365nm is the 'peak' frequency to look for. Let’s find a ~365nm SMT UV LED we can pick and place onto a small PCB for easy sewing. ✨🧵 ----------------------------------------- Visit the Adafruit shop online - http://www.adafruit.com LIVE CHAT IS HERE! http://adafru.it/discord Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ ----------------------------------------- #ElectronicsDesign #UVLED #TheGreatSearch…

EYE ON NPI – onsemi NIV3071 4-Channel eFuse Solution 7:58

۹ روز پیش7:58

7:58

This week's EYE ON NPI is another onsemi device - this week we're looking at the NIV3071 4-Channel eFuse Solution (https://www.digikey.com/en/product-highlight/o/on-semi/niv3071-4-channel-efuse-solution) a power distribution manager that can lets you manage a product with a lot of power domains and supplies using just a couple GPIO pins. This week's product is an upgrade from the covered-earlier NIS5420 (https://blog.adafruit.com/2021/09/09/eye-on-npi-onsemi-efuse-porfolio-eyeonnpi-digikey-onsemi-digikey-adafruit/) - with a higher 8~60V input range, and 4 independently-controlled channels. When people first meet fuses, they usually see and think of classic 'wire' fuses (https://www.digikey.com/en/products/detail/bel-fuse-inc/5ST-200-R/1009012) with ceramic or glass or thermoplastic bodies, and a thin wire inside. When too much current goes through the fuse wire, it gets hotter and hotter and eventually melts, cutting off the load from the source voltage. These kinds of fuses are super cheap, very-very-low resistance, easy to find at any hardware store, and there's lots of suppliers with various current limits. However, they're one-shot usage only and only good for over-current, can't act as switches/sequencers. You need to have a way for customers to access the fuse in order to replace it. For those reasons, a lot of engineers prefer going with 'poly fuses' - fuses that are easy to mount into a circuit that auto-reset after a time (usually minutes) so that a temporary overload doesn't make the device a brick so quickly. For example, we have a chunky 24V 5A hold / 10 A trip polyfuse (https://www.digikey.com/en/products/detail/littelfuse-inc/2016L260-24MR/6347052) on the Sparkle Motion board design (https://www.adafruit.com/product/6100), designed to protect folks who accidentally have a short in the output LED strings, and want to avoid damaging the power supply or main board. Poly-fuses are a great step-up from plain wire fuses: they're fairly inexpensive, available from lots of suppliers with various current limits, and best of all the fuse auto-resets after cooling down. However, like wire fuses, they're good for over-current, can't be reset, and have some variation depending on ambient temperature: you may trip 50% higher if its cold, or lower if its hot. Thus the next generation of fuses: eFuses (https://www.digikey.com/en/product-highlight/o/on-semi/efuse-automotive-circuit-protection)! As you could imagine, these are pure-silicon fuses, with a chunky N-FET that acts as the cut-off switch, and current limiting managed as an analog feedback loop that will cut the FET when too high. We get the resetability of a polyfuse, with additional control like sequence-able enable pins and under-voltage lockout. Note that some eFuses also can do over-voltage clamps and negative voltage protection, but the NIV3071 (https://www.digikey.com/short/3v0thr1p) doesn't contain these protections, so you may want to implement those protections separately. Especially designed for automotive power systems, which tend to be 12V/24V/36V/48V multiples, the NIV3071 (https://www.digikey.com/short/3v0thr1p) is AEC−Q100 qualified and PPAP capable (https://www.onsemi.com/pub/collateral/tnd6284-d.pdf). The use of eFuses is becoming popular as cars have become more computerized and electrified, with each 'zone' in a car (https://www.onsemi.com/solutions/automotive/zonal-architecture) - such as entertainment, communication, lighting, charging and sensors - all needing separate power management. If you don't need automotive qualifications, the functionally-compatible NIS3071 (https://www.digikey.com/short/9v2dmvhf) is a couple of cents cheaper. This family of eFuses is good for up to 60V and 2.5A per channel, but if you need more per channel you can just double or triple them up to add 2.5A per. If you want less per channel, to protect low-power devices from overheating or accidental shorts, the current limit can be reduced with an external resistor. And of course, you can turn on/off each channel with a GPIO enable pin: great for sequencing your power chain to reduce stress on the power supply from inrush current, or to allow each section to stabilize and go through self-test. For your next power supply design, the onsemi NIV3071 (https://www.digikey.com/short/3v0thr1p) and NIS3071 (https://www.digikey.com/short/9v2dmvhf) offer high-voltage, high-current control in a small package and a great price. Both are in stock right now at DigiKey for immediate shipment, so you can book today and start integration by tomorrow afternoon.…

The Great Search – 4.7 µH RF Inductor Q greater than 20 at 25 MHz 9:53

12 روز پیش9:53

9:53

For our SI4732 radio breakout, we're following the application note (https://www.skyworksinc.com/-/media/Skyworks/SL/documents/public/application-notes/AN383.pdf) for antenna setup. It specifies a low-pass filter inductor of 4.7 µH with a Q factor greater than 20 at 25 MHz and minimal DC resistance. The recommended part, COILCRAFT 1008CS-472GLB (https://www.digikey.com/en/products/detail/coilcraft/1008CS-472XGRC/15794541), is somewhat pricey. Let's explore some alternatives! Recommended Alternatives: Murata LQW2UAS4R7J00L: 4.7 µH, Q=20 @25 MHz, 260 mA, 4 Ω DCR, 1008 package. Abracon AISC-1008-4R7J-T: 4.7 µH, Q=20 @25 MHz, 260 mA, 4 Ω DCR, 1008 package. Murata LQW32FT4R7M8HL: 4.7 µH, Q=30 @25 MHz, 400 mA, 1.2 Ω DCR, 1210 package.…

Trying out Claude Code with Sonnet 4 for our STSPIN220 library 🌀🤖🔧 3:31

14 روز پیش3:31

3:31

We got the drop that Sonnet 4 (https://www.anthropic.com/news/claude-4) just got released and the baby went to sleep early, so let's try it out! We wrote a library for the STSPIN220 (https://www.digikey.com/en/products/detail/stmicroelectronics/STSPIN220/6137574) — this is a stepper motor driver like the A4988 (https://www.adafruit.com/product/6109) or TMC2209 (https://www.adafruit.com/product/6121), but for low voltage motors. One interesting thing about it is it uses the step/dir and two mode pins to set the micro-steps, from 1 to 1/256. Since that gets a little confusing, we figured a driver (https://github.com/adafruit/Adafruit_STSPIN) would be worth doing. The table was definitely annoying to decode, and higher microsteps started overflowing 16-bit variables, but now we've got it spinning happily! #anthropic #claude #sonnet Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------…
