# 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.

    Radio Connection

  • 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 (opens new window) (PPM-Sum receivers use a single signal wire for all channels).

# 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).
