Interface notes
|
|
---------------
|
|
|
|
- UART2 is enabled as the default console.
|
|
- Pin 37 is occupied by the audio I2S device, as such it is currently unavailable as GPIO.
|
|
- All UART ports support baud up to 1500000.
|
|
- Pin 3 & 5 are connected to the 3.3V supply through a 2.2K pull-up resistor to support I2C function. As such they cannot be used as GPIO.

Pin Mapping
|
|
-----------
|
|
|
|
Radxa ROCK 3 Model C has a 40-pin expansion header. Each pin is distinguished by the color.
