“Beautiful little board. So simple to use (as is the whole breakout garden range) in both C and Micropython on the Pi Pico with either the Explorer base or the Pico breakout garden pack. I've been playing with it displaying different colours depending on the temperature read from the BME270 breakout on a Pico in C and it's great fun.”
“with the Breakout Garden, ths was really easy to hook up and actvate. to make it even easier, I wrote a Node-RED node to allow it to be controlled with flow-based programming.

“The LEDs are bright and the Matrix is easy to controll with the python library. The only problem I had is that there is no documentation of the library but with the examples on GitHub I was able to figure everything out.”
