This week's EYE ON NPI is caring and sensitive... Conductive Containers' Corstat® (https://www.digikey.com/en/product-highlight/c/conductive-containers/conductive-pcb-mailers) and PillowStat (https://www.digikey.com/en/product-highlight/c/conductive-containers/pillowstat-injection-molded-component-cases) mailers are soft and ESD-safe, so they will never break your heart or give your delicate electronics a nasty shock! After manufacturing, you'll need to get your boards to a final manufacturing or packaging facility. Or, your boards may be sold 'bare' to the end user. That's where these mailers come in to save the day: they are durable, and fully ESD-safe with coated cardboard and foam. We've seen chips and displays arrive to us in Corstat mailers, but it somehow never crossed our minds that we could buy them off the shelf! Conductive Containers (https://www.digikey.com/en/supplier-centers/conductive-containers) are experts at ESD things of all shapes, sizes and extrusions. We're doing a 2-for-1 on this EYE ON NPI, highlighting both their 'convoluted pink foam' (https://www.digikey.com/en/product-highlight/c/conductive-containers/conductive-pcb-mailers) and 'flat black folding-mailers' (https://www.digikey.com/en/product-highlight/c/conductive-containers/pillowstat-injection-molded-component-cases) If you have special packaging needs, you can always contact CCI for custom sizing, but their 'off the shelf' packages come in a range of sizes and you can get them instantly in almost any quantity, thanks to their fabrication facilities in the US (CCI also makes all sorts of other ESD handling/storage items which we use here at Adafruit for holding reels and components.) We like that these boxes in that you don't have to antistat, bubble bag and separately box: it's an all-in-one step. And the boxes ship nice and flat, with good creases, so they're very fast to assemble. Digi-Key carries a wide size range of both Corstat® and PillowStat mailers (https://www.digikey.com/en/supplier-centers/conductive-containers) so full PCB assemblies and individual components can be packaged safely. Order any Conductive Containers from stock (https://www.digikey.com/short/vwpz3ht7) today and you can have packaging problems solved by tomorrow afternoon!

We sat down today to do the mapping for our LED glasses which have both rings and a planar matrix. Mapping LEDs or pixels is one of those time-worn tasks that we often end up grinding through - we'll chat about how we made it go fast! Also, an unboxing of a Paper Shoot camera, these are low cost 'DIY' cameras that come with a bare PCB and a foldable case. There's 4 filters you can apply to the camera output and there's no TFT - just a cutout viewfinder. Let's take a look at what we can find on the PCB itself The Great Search - SP4T Slide Switch https://www.digikey.com/short/f2p4hwjb The Paper Shoot camera we did an unboxing of has a nifty SP4T slide switch.

This week's EYE ON NPI is ready to be part of your tag-team crew: it's ST's ST25DV-I2C-EVO Dynamic NFC/RFID Tags IC (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/st25dv-i2c-evo-dynamic-nfc-rfid-tags-ic), available in a few different memory sizes. We're psyched to get to feature this chip on EYE ON NPI because we found an earlier version of these chips -- the ST25DV16K (https://www.digikey.com/en/products/detail/stmicroelectronics/ST25DV16K-IER6T3/6691420) -- a few months ago and made a STEMMA QT breakout for it (https://www.digikey.com/en/products/detail/adafruit-industries-llc/4701/13688447). Even though at the time we sorta thought this would be a niche product it turns out it's quite popular thanks to the straight-forward simplicity Basically, this chip is a 'smart' RFID/NFC tag. Normally, when you think of an NFC tag, you'd picture one of these RFID cards (https://www.adafruit.com/product/4034) or stickers (https://www.adafruit.com/product/4032). These are small chips that have built in memory that can be read or written when self-powered by an RFID field. One of the neat things is that they are electronic devices that do not get powered by a battery. Don't get us wrong, we really like batteries but they are real pain to manage - you have to manage sleep stages, recharging, under/over voltage, chemical leaks, etc. Low power management is really hard. The nifty thing about RF-powered electronics is how many problems they 'solve': by default they draw no power, so you don't have to worry about sleep modes. There's no battery, so no recharging or replacement needed. They only turn on when physically close to the reader, and auto-turn-off when the reader is away - the UX is intuitive and does not require any buttons. Most tags and cards address a static chunk of memory, maybe a few K in size. You touch to write/read or authenticate. They're super cheap, easy to embed in every credit card. However, they often don't do anything other than the read/write/auth behaviors - it isn't possible to expand the capabilities since there's only a couple different chips. That's where the ST25DV series (https://www.digikey.com/en/product-highlight/s/stmicroelectronics/st25dv-i2c-evo-dynamic-nfc-rfid-tags-ic) comes in! The ST25 series looks just like an ISO 15693 tag (https://en.wikipedia.org/wiki/ISO/IEC_15693) to a reader, but there's also an I2C interface that can be used to easily change the memory contents. This means its a fast and mobile-friendly way to transmit data back and forth without a massive amount of development to handle the data encapsulation. Both Android and iOS have built in NFC support for this tag format and you can easily query/write data via the NFC API. ISO 15693 has a specification of up to 1 meter (when used with a large-antenna RFID reader), a few inches from a phone. For the antenna design, ST has a nice eDesignSuite website that will do all the math for you, to create an antenna tuned to the size you have available (https://www.st.com/content/st_com/en/support/resources/edesign.html) Even if your product does have a battery, say for a datalogging system, using NFC for data transfer will use a lot less power than BLE or WiFi - and without the mess of differentiating many nearby devices, BLE pairing, or wireless/cellular credentials & deployment. And usage is super simple - we were grateful to see an Arduino library written by ST with an instant gratification example (https://github.com/stm32duino/ST25DV). Thanks to I2C's universality, the code can be ported to any microcontroller. If your microcontroller is a low-power device, you may be able to use the energy harvesting output from the ST25 chip to power your circuitry. Depending on the EM field strength, you can get up to about 3V at 1mA or 7mA at 2.3V (https://docplayer.net/169359266-Nfc-rfid-st25-product-overview.html) You can order these in a few different SMT packages and sizes from Digi-Key - the SOIC and TSSOP packages are available now with 4Kbit, 16Kbit and 64Kbit memory size. (https://www.digikey.com/en/products/filter/rfid-rf-access-monitoring-ics/880?s=N4IgTCBcDaIMoBUwFYAiA1EBdAvkA) The new KC series seems to add the ability to change the I2C address, but if you don't need that, the plain K series is pin compatible as well. We recommend starting with the SOIC version of the ST25DV16KC (https://www.digikey.com/short/jt4h3rrh) for an easy-to-solder starter chip. It's in stock and ready to ship immediately from Digi-Key - order today and you can be NFC'ing by tomorrow afternoon!

Yay our IS31FL3741 PCB is finally fabbed - we made some with two different LEDs to compare. Thankfully our yield was 100% for the 4 panels we manufactured. Next up we're going to test out and bring up our LED glasses design which is basically a mechanically 'deconstructed' version of the same board. Most annoying part? Doing the LED mapping! We actually found its easier to do that in CircuitPython first since we need to do very fast iteration. Special Request!

When you start putting a ton of RGB LEDs on a board, the price of 'smart' pixel LEDs like NeoPixels & DotStars starts to add up. That's why we fancy this IS31FL3741 breakout, which has 117 RGB common-anode LEDs, each one controlled with 8-bit-per-channel PWM. At a penny or two per, we can sell this board for a reasonable price and its fully controllable over I2C. #comingsoon #adafruit #IS31FL3741 Visit the Adafruit shop online - http://www.adafruit.com ----------------------------------------- LIVE CHAT IS HERE! http://adafru.it/discord Adafruit on Instagram: https://www.instagram.com/adafruit Subscribe to Adafruit on YouTube: http://adafru.it/subscribe New tutorials on the Adafruit Learning System: http://learn.adafruit.com/ -----------------------------------------
