I’m working on a MFE Believer for aerial imagery, and I’ve got a Pixhawk 4 running Ardupilot, and the Seagull #MAP2 and #SYNC2. I’m currently using the PM07 board with the (confusing for me) Pixhawk 4 I/O PWM OUT running through the PM07 FMU PWM-IN --> FMU PWM-OUT for servo control and ESC controls. I have the MAIN 1-5 (IO_CH1 - IO_CH5) fitted with these, and the BEC leg of the ESC providing 5v to the rail, leaving 3 MAIN pins open (IO_CH6 -IO_CH8). I still have the 8 pins available from the Pixhawk 4’s FMU PWM OUT(FMU_CH1- FMU_CH8), but I’m not sure how I can use these as the AUX pins, or where to assign them in mission planner. Any advice would be appreciated!
