Refer to pinouts for pinouts

UART

The Open.OC2 carrier board brings out several of the Jetson's UART interfaces which can be used to communicate with external devices.

J2 (Debug)

Device path /dev/ttyS0
Voltage level 3.3V
Jetson name UART2
Remarks 1.8V on Jetson module, shifted to 3.3V by SN74AVC4T245
Boots into console, can be used for debugging during boot

ESP-WROOM-02

Device path /dev/ttyTHS1
Voltage level 3.3V
Jetson name UART1
Remarks 1.8V on Jetson module, shifted to 3.3V by SN74AVC4T245
Connected to ESP-WROOM-02 module, used to flash or communicate with ESP-WROOM-02 module, see XXX (PAGE) for details

Cube

Device path /dev/ttyTHS2
Voltage level 3.3V
Jetson name UART0
Remarks 1.8V on Jetson module, shifted to 3.3V by SN74AVC4T245
Connected to Cube flight controller (SERIALXXX) used to flash or communicate with Cube, see XXX (PAGE) for details

I2C

SPI
