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 |
