 OpenPuck is an opensource firmware for NRF52840 Pro Micro that copycats the Steam Controller 2 Puck and allows emulation of Xbox, Switch, and PS3/4/5 controllers and also includes an independant lizard mode (which can work on UAC prompts/task manager/etc). The Switch and PS3 modes have been verified to work on real consoles and Switch, PS4/5 modes have gyro (and touchpad where available) hooked in. Back 4 buttons are mappable for all emulated modes.
