This reference lists the output port to motor/servo mapping for all supported air and ground frames (if your frame is not listed in the reference then use a "generic" airframe of the correct type). Motors and servos are connected to the MAIN OUT ports in the order specified for your vehicle in the Airframe Reference. Digital Airspeed Sensor (opens new window) some with cable and Dupont connectors, and some USB TTL type connectors on a PCB with male or female Dupont pin connectors for USB-A, mini or micro USB.Please refer to the wiring page for details of how to wire up this port. The pinout uses the standard Pixhawk debug connector (opens new window) pinout. The port has a standard serial pinout and can be connected to a standard FTDI cable (3.3V, but it's 5V tolerant) or a Dronecode probe (opens new window). In order to access these ports, the user must remove the Pixhawk 4 Mini casing. The PX4 System Console and SWD interface run on the FMU Debug port. Analog inputs for voltage / current of batteryĪdditional information can be found in the Pixhawk 4 Mini Technical Data Sheet (opens new window).NRZI (Non Return to Zero Invert) encoding scheme used to send data with a sync field to synchronise the host and receiver clocks. Dedicated R/C input for Spektrum / DSM and S.Bus with analog / PWM RSSI input Micro-USB cable uses 4 shielded wires: two for power (+5v & GND), two for differential data signals (labelled as D+ and D- in pinout).GPS: u-blox Neo-M8N GPS/GLONASS receiver integrated magnetometer IST8310.32 Bit Arm® Cortex®-M7, 216MHz, 2MB memory, 512KB RAM.This autopilot is supported by the PX4 maintenance and test teams.
