Our friends at Oak Development Tech designed this WiFi + RGB matrix display which combines the power of ESP32-S2 and SK6812mini:

PixelWing ESP32-S2 RGB Matrix

The PixelWing Matrix is a powerful ESP32-S2 RGB Matrix Display board that allows you to make a simple connected display, data logger, or environmental indicator. The PixelWing features USB-C power, a 5×10 RGB Matrix Display using SK6812mini Addressable LEDs that are compatible with Adafruit NEOPIXEL Libraries!
In addition to this, the PixelWing provides a quick access I2C JST connector that is compatible with Qwiic and Stemma QT connectors allowing you to connect all your favorite Adafruit and Sparkfun sensor breakouts.
All of this is combined with Circuit Python support making it easy to get programming on your project.

Sometime in the next 2ish weeks we’ll be bringing the PixelWing to our shop! We hope you’re ready! 🙂 if we hit 1000 followers by August 15th we’ll give 1 PixelWing to a lucky follower! 🙂 pic.twitter.com/vT3iLMByFA

Stepper Motor FeatherWing

August 2, 2020 fustinifeatherwing, hackaday.ioLeave a comment

Lex Kravitz has designed a simple board containing the ULN2003 stepper motor driver in a Feather form factor:

Feather ULN2003 Stepper Wing

This Feather Wing was made to be hand assembled with through-hole components, which I find easier to put together in small runs. In the future I may make a version with SMD components as well for professional manufacture. I made this to control 5V 28BYJ-48 steppers that are easily available for ~$2-3 each. Often they come with a ULN2003 driver board, if you are thrifty you can grab the chip off the board and move it to this board saving ~50 cents per board.

This board contains:

1) Two 3-pin headers (GND, PWR, and SIG). These can be used to control a servo or additional sensor.

2) A 3.5mm TRRS port for external control

3) Two LEDs tied to digital pins

4) The ULN2003 motor driver

5) Two small buttons for user control

Thanks for the tweet @oshpark! And thanks for making the PCBs! Here's another video of this little board dispensing M&Ms 🙂 https://t.co/Ep8G8GaXYd

The nRF9160 Feather Is Now Served

Jared Wolff has design a Feather form factor board with the nRF9160:

The nRF9160 Feather Is Now Served

Low-power shutdown, built-in 4FF SIM card slot, flexible power supply, and more.

I was a complete failure. My prototype wasn’t working. I spent at least an hour trying to rework a frustratingly large LTE module on an impossibly small circuit board.

It wasn’t going to work.

So I went back to the drawing board. I poured my years of hardware experience into a tiny form factor.

The end product?

Something smart. Something with LTE, NB-IoT, and GPS. Something anyone could get started with right away.

And thus, the nRF9160 Feather was born.

I need your help! 🙏

To make this campaign a reality, I need your help to meet our minimum order quantity of nRF9160 Feathers. Without that, we’re dead in the water! Head on over to the campaign page to reserve yours.

For those of you who’ve already committed, I thank you from the bottom of my heart. I can’t wait to get the nRF9160 Feather into your hands!

P.S. Huge thanks to Hackster and GroupGets for making this happen. You guys and girls are great. ❤
