This module enables Gadgeteer to communicate with MIDI synthesizers, sound modules, keyboards, sequencers and more. Supports MIDI-IN and MIDI-OUT. Additional pin header included for using with non-Gadgeteer boards. Unlike most MIDI modules, this one was specificially designed to work correctly with 3.3v to 5v microcontrollers (most only work with 5v as MIDI is a 5v protocol).
You can see a video of the prototype module in action on YouTube.
