This board doesn't have DIN MIDI connectors, so they have to be added to the board with the corresponding circuitry. Use this schematic:
| MIDI In | MIDI out |
|---|---|
| GPIO41 | GPIO40 |
| Screen | Pin |
|---|---|
| Vcc | 5V |
| GND | GND |
| Rx | GPIO40 |
| Tx | GPIO41 |
Hold OpenDeck switch 0 / GPIO2 low while resetting or powering the board to
enter the OpenDeck bootloader.
To flash this board with the OpenDeck firmware, go to the OpenDeck configurator and follow the instructions.
DIN MIDI and touchscreen use the same UART pins on this board, so only one of them can be enabled at a time.
