Teensyboy Pro

Regular price $60.00

Teensyboy Pro has been discontinued! Check out the new Arduinoboy Pro Micro for an updated version of the Teensyboy Pro!

Teensyboy Pro is a MIDI interface for the Nintendo Gameboy. It features a variety of modes to accommodate LSDJ, Nanoloop, and mGB. The Teensyboy Pro is intended to replace my Arduinoboy. It is functionally compatible with Arduinoboy, but has USB MIDI in addition to traditional DIN MIDI. For more information, see the Arduinoboy readme. For power and connectivity, you’ll need a standard micro USB cable (not included).

The Quickstart bundle includes a cartridge with mGB and a dual link cable for a Gameboy Classic/Pocket/Color/Advance. It contains everything you need to rock out with your Gameboy!

Here is a table that explains the difference between various Arduinoboy models:

Variant Price USB MIDI DIN MIDI Notes
Arduinoboy $16-$22 (kit) DIY kit only.
Arduinoboy Lite $25 ✔ (out only) Uses special fork of Arduinoboy code the improves midi out, but only does midi out.

Arduinoboy Pro
