This quick start guide shows how to power the Pixracer flight controller and connect its most important peripherals.
Wiring Guides/Assembly
Main Setup
Radio/Remote Control
A remote control (RC) radio system is required if you want to manually control your vehicle (PX4 does not require a radio system for autonomous flight modes).
You will need to select a compatible transmitter/receiver and then bind them so that they communicate (read the instructions that come with your specific transmitter/receiver).
The instructions below show how to connect the different types of receivers:
FrSky receivers connect via the port shown, and can use the provided I/O Connector.
PPM-SUM and S.BUS receivers connect to the RCIN port.
PPM and PWM receivers that have an individual wire for each channel must connect to the RCIN port via a PPM encoder like this one (PPM-Sum receivers use a single signal wire for all channels).
Power Module (ACSP4)
External Telemetry
Pixracer has inbuilt WiFi, but also supports telemetry via external Wi-Fi or radio telemetry modules connected to the TELEM1 or TELEM2 ports. This is shown in the wiring diagram below.
:::note The TELEM2 port must be configured as a second MAVLink instance using the MAV_2_CONFIG parameter. For more information see MAVLink Peripherals > MAVLink Instances (and Serial Port Configuration). :::
