A USB device that receives commands from a smartphone over USB-MIDI and
emulates retro-PC HID peripherals (ATARI joystick, Sega Mega Drive
6-button pad, Sharp X68000 keyboard and mouse). Built around the WCH
CH32X035 MCU. The firmware is Apache-2.0; the board designs are published
at <https://github.com/kunichiko/MimicX-hardware> under CERN-OHL-S-2.0,
with schematics-equivalent block diagrams, PCB layer plots and photos of the
assembled hardware.

A wireless/wired bridge variant of Mimic X: an ESP32 module (C6 / S3 / C3)
exposes a
USB-MIDI device (TinyUSB) and a BLE-MIDI peripheral simultaneously, and
relays MIDI/SysEx to the CH32X035-based Mimic X device engine over I2C.
Emulates retro-PC HID peripherals (ATARI joystick, Sega Mega Drive
6-button pad, Sharp X68000 keyboard and mouse). The firmware is Apache-2.0;
the board designs are published at
<https://github.com/kunichiko/MimicX-hardware> under CERN-OHL-S-2.0.
