Game Boy MIDI USB-C Host Adaptor

An updated version of the trash80 ArduinoBoy hardware.

…with a USB-C host port to plug in and power a keyboard!

Connect a USB MIDI keyboard right to your Game Boy without a computer in-between. Or, connect it to a computer as a driver-free MIDI device. Good ol’ TRS MIDI jacks are here too.

It also fits perfectly in a GBA game case!

Coming July 2026! Stay tuned! PCBs in production now.
