J2 UART Pin header
Connected to the U0RXD, U0TXD system UART of the ESP32-C3. Currently not used on this board.
It can be used as GPIO through appropriate configuration in esp-idf.
J3 ODROID UART Connector
Connects to the UART debug port of the ODROID.
This connector is X8821WRS-04. you can use the cable from the USB-UART 2 board.
J4 GPIO Output

| Pin Number | Function | Function | Pin Number |
|---|---|---|---|
| 3 | Reserved | Reserved | 1 |
| 4 | Reset (Open Drain) | Power (Open Drain) | 2 |
The Reset and Power pins can be used on the ODROID-M series and H series.
J5 DC Input
Supports 9~21v input. You can use the DC power supply sold by Hardkernel.
J6 DC Out
Outputs the switched power from the J5 input.
J7 USB Power Out
Switched 5v voltage output. The output is set to 5.25V considering voltage drop. Please use with caution.
J8 OLED Display Connector
Reserved
SSD1309 OLED Connector
It cannot be used as GPIO for other purposes because it shares the I2C bus with PCA9557PW, INA3221.
