Description

clumsyMIDI - Raspberry Pi expansion board

A Raspberry Pi expansion board containing a MIDI interface, DAC, and OLED display requiring only through-hole soldering skills. This is primarily intended as an all-in-one hardware solution for the mt32-pi Roland MT-32 emulator but all features are usable with Raspberry Pi OS, too.

Features

TI PCM5102 I2S HiFi DAC (using the ubiquitous GY-PCM5102 carrier board)
GPIO MIDI interface with in, out, and thru
0.91" OLED display
large-ish 5V bypass capacitor which may help with slightly weak power supplies
works with mt32-pi and Raspberry Pi OS
no SMT soldering required, suitable for DIY electronics beginners and clumsy people ;)
