Game Boy MIDI USB-C Host Adaptor

ARDUINOBOY HOST EDITION

Game Boy MIDI USB-C Host Adaptor • Available Now!

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. Classic DIN MIDI jacks will be part of the upcoming enclosure design.

It also fits perfectly in a GBA game case!

July 24, 2026 UPDATE: First-gen PCB is available now! Soon there will be an enclosure with DIN MIDI ports as well. The next generation PCB has a slightly smaller DMG port and a pin polarity fix on both ports. Because of this, the first-run demo units have a couple bodge-wires and the DMG port has been shaved smaller slightly by hand.

Final release version is coming fall 2026! Stay tuned!

Contact me for a free first-run demo unit in exchange for a social media post or a video review I can share.
