GPS
GPS is a UBlox M8N with blue wires. It plugs into the GPS2 port and must be placed as far as possible from the other electronics. Orientation is not important, only that the antenna must be facing up.
Power Module
Power Module (black box, WARG logo on it) has main XT90 connectors for power and long black wires for Pixhawk power and signals. One plug fits in the POWER1 port and the other into the AD&IO port.
RFD900X
The RFD900X plugs into the TELEM2 port. The RC OUT (Dark Blue) wire goes to RC IN on the Pixhawk. This is likley to change in the future when we have the ability to power the RFD900X externally. If any of the wires come undone on the RFD900X side then refer to the photo below to see what colour goes where.
Motors/Servos
Connect Pixhawk to PC, open Mission Planner, and connect. Go to Setup tab, servo outputs. It shows which motor/servo goes where. Only the FMU ports support DSHOT, I/O ports support only PWM. They must be set in blocks, so no PWM devices can be connected to the FMU ports and vice versa. Below is a diagram showing motor numbers and the intended spin direction. (Note this is opposite what is typically used for a quad)
Future Peripherals
HereFlow Optical Flow Sensor: CAN1
Benewake TFmini LIDAR: I2C
Safety Switch/LED: GPS1
Holybro OSD: TELEM3 (if free), RX only TELEM2 (if TELEM3 taken)
TELEM1 might be for landing commands from ZP/CV
