Flight Core v2 Telemetry
Table of contents
Hardware
J1 - TELEM1
UART7 is exposed on J1, which is mapped to TELEM1 in PX4 and available to Nuttx as /dev/ttyS6.
This is the default port used by the ModalAI UART ESC Driver when enabled. When the UART ESC is not enabled, this can be used to interface with as a typical telemetry port.
PLEASE NOTE in 1.13.2-0.1.1 and older, the default ESC port was J5.

J5 - TELEM2
UART5 is exposed on J5, which is mapped to TELEM2 in PX4 and available to Nuttx as /dev/ttyS4.
Recommended is MCBL-00066 (6p to 4p JST UART Cable) for this interface.
PLEASE NOTE in 1.13.2-0.1.1 and older, this port was used as default ModalAI ESC, which changed to J1.
