I like this nice small I2C controller very much. In fact it is the second I bought from Pimoroni. I had already experience with an Adafruit Seesaw Gamepad with 6 buttons and a joystick. This QwstPad controller however has ten buttons to use and four LEDs that one all can control; an I2C address you can chose off. You can also daisy chain connect the controlers because the board has two Qs/ST connectors. Yesterday I finished to write a port for C++ / Arduino and wrote a test sketch to show and check the working of my C++ library. The Pimoroni qwstpad-micropython I used as an example to port to C++. Thanks Pimoroni for excellent Products, service and all the software that you make available for your products. Btw: happy 13th anniverasary!
