My pull requests just got merged into CircuitPython. One is the for the Trinket M0 with a hacked on flash chip — it's now called Trinket M0 Haxpress, and the other one is adding a gamepad module with functions for scanning and de-bouncing button presses.

I'm now waiting for the version 4.1 prototype PCB and parts, and once that works, I can make the custom firmware for it and start working on the sound support in the library.
