Internal Expansion UART
The internal port is prewired with a cable made available inside of the chassis. The connector
is a JST GH 6 pin connector matching the standard dronecode/PX4 pinout. It is paired with a
standard 4 pin GH CANbus connector for peripheral CANbus connections.
The internal port is shared with the WIFI module. To enable it for external communications
use, you must ensure WIFI is disabled using the parameter “FF_WIFI_ENABLE”. WIFI is
disabled by default, which means external communications are enabled. The internal port
uses 921600 baud 8-N-1 by default but is modifiable using parameter “SER_TEL2_BAUD”.
This UART can be configured as a MAVLink “onboard” port, which enables a group of
standard MAVLink streams for communication with an onboard companion computer.
