The Adafruit MIDI FeatherWing Kit adds MIDI input and output to any compatible Feather board. Featuring both DIN-5 MIDI jacks, a 3.3V optical isolator for safe MIDI input, and indicator LEDs for transmit/receive activity, this FeatherWing makes it easy to build MIDI controllers, synthesisers, and musical instruments.

The FeatherWing uses the hardware UART (RX/TX pins) at 31,250 baud for MIDI communication. Optional solder pads are provided for 3.5mm TRS MIDI A stereo jacks if you prefer the compact connector format.

Key Features

• MIDI In + MIDI Out – Both DIN-5 jacks included for full bidirectional MIDI
• 3.3V Optical Isolator – Safe MIDI input for 3.3V logic Feather boards
• Activity LEDs – Indicator LEDs under each jack show data transmission and reception
• Hardware UART Interface – Uses RX/TX pins at 31,250 baud
• Optional TRS MIDI A Support – Solder pads for 3.5mm stereo jacks (jacks not included)
• Feather Compatible – Works with any Feather board that has native USB
