VOXL2-MINI Serial Pin Mapping for Ardupilot

TomP · 26 Mar 2025, 21:11

Which pins on the J19 connector of the VOXL2-Mini are mapped to ArduPilot's SERIALx ports?

For the VOXL2-Mini J19 connector, one of the UART connections (pins 7 and is reserved for PWM signals. With pins 2 and 3 dedicated to GPS, which ArduPilot SERIALx port does that correspond to? Additionally, which SERIALx port is mapped to pins 10 and 11?

Best regards,
Tom

@TomP GPS on pins 2 and 3 is mapped to serial port 3 in ArduPilot. The RC port on pins 10 and 11 is mapped to 4. https://github.com/ArduPilot/ardupilot/blob/d977f318c68faf69b8afa9b5c1afe73932a1d946/libraries/AP_HAL_QURT/HAL_QURT_Class.cpp#L50
