“Was looking for a simple way to drive lots of arcade button LEDs, and found this board. Really easy to use with the Arduino library, had a quick test up and running in only a few minutes. Think I might need a couple more!”
“Very friendly GPIO expander. I used to control 16 LEDs, so that I could free up 16 GPIO outputs on a Pico Pi.
Worked brilliantly, but not with the CircuitPython in the way I needed. I wanted to talk to it in Micropython because I had a lot of existing code to integrate with. I found a wonderful French guy who had translated the datasheet info across to Micropython to start me off...

Brilliant!!”
