This is not a full source/build, but meant two files you can update that adds initial boop support. Get it going with something like:
rshell rsync ./src /
rshell "repl ~ import machine ~ machine.soft_reset() ~"
The Schematic is located in this PDF: DCF31BadgeSchematic.pdf

This is the initial release firmware on the badges.
This is the new MicroPython firmware.
