About a month ago, I came across an interesting little ESP32-C3 powered board on Twitter. One side is covered in a 5x5 grid of WS2812B LEDs, making for some fun opportunities for creative hacks.
The boards come pre-loaded with an Arduino sketch for the ESP32 core, but we've found that the MicroPython ESP32-C3 port runs nicely (barring some adjustments that were recently made to the RMT code that enables the LEDs to be addressed correctly).
I've written up a couple of blog posts:
- Bringing the bling with MicroPython (blog post, with background)
- Making a CheerDot with MicroPython
I've also got all of the MicroPython code and my notes on GitHub, if you're curious. I'm a relative newcomer in the MicroPython space, so I'm curious to learn from the rest of the community.
Thanks for reading
