Condition: 100% Brand New Item Type: MIDI Module Material: PCB Pin Length: Approx. 2.54mm / 0.1in 1Through the MIDI adapter board, other microcontroller can access the powerful MIDI communication protocol. The MIDI protocol and asynchronous serial interface have many similarities, so users can use the microcontroller UART pins to send MIDI event messages. 2The MIDI adapter board provides MIDI?IN and MIDI?OUT connections and MIDI THRU ports. The MIDI?port is light IN isolation to prevent ground loops. The MIDI adapter board can be installed directly like the shield on the top of the board: connect MIDI?IN/THRU to the hardware RX pin, and connect MIDI?OUT to TX. Its data and analog pins, power bus and bus can be transferred out. 3The RUN / PGM switch allows users to program the serial port of the for board without disassembling the board. Note: The three?hole MIDI connector is not soldered on the MIDI adapter board, but these connectors are included in this product. 4The 2.54mm pin headers on both sides of the extension can be easily connected to your project. Simple to operate. MIDI IN switch, you can turn off data reception. 5Made of high?quality PCB material, safe and durable in use, has a long service life. Small and pratical, rapid and efficient.1 x Serial Port toMIDI Module
