2	3V	GP28	GND with 1k resistor

PWM outputs

Note: current-limiting resistors for LEDs are required in order to avoid damage to the board.

Output #	Anode	Cathode
0	GP14	GND
1	GP15	GND
2	GP22	GND
3	GP21	GND
4	GP20	GND
5	GP19	GND
6	GP18	GND

Traffic indicators

Indicator	LED
USB input	GP25
USB output	GP25
DIN input	GP25
DIN output	GP25

I2C

Signal	Pin
Vcc	3V
GND	GND
SDA	GP16
SCL	GP17

DIN MIDI

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
GP1	GP0

Touchscreen

Screen	Pin
Vcc	5V
GND	GND
Rx	GP5
Tx	GP4

Bootloader switch

Hold OpenDeck switch 0 / GP2 low while resetting or powering the board to enter the OpenDeck bootloader.

Flashing

To flash this board with the OpenDeck firmware, go to the OpenDeck configurator and follow the instructions.
