Description
This is a replacement board for Korg MicroKey 37 midi keyboard. ArduinoPro Micro and serial port expander (CJMCU-2317) has been used. Only one USB, no HUB like on the original.
Connectors:
P1 is theVCC and GND connector for the scan matrix
P2 is the 8 rows of the scan matrix
P3 is the column selector
P4 is the pitch and modulation wheel potentiometers
P5 is the octave selectro buttons and LEDs
