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 |

| 7 | 8 |
| Screen | Pin |
|---|---|
| Vcc | 5V |
| GND | GND |
| Rx | 8 |
| Tx | 7 |
Hold OpenDeck switch 0 / 2 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.
The teensy4 target uses several underside-only pads on Teensy 4.0: 34,
35, 36, 37, and 38.
DIN MIDI and touchscreen use the same UART pins on this board, so only one of them can be enabled at a time.
