Kit

The Pixracer is designed to use a separate avionics power supply. This is necessary to avoid current surges from motors or ESCs to flow back to the flight controller and disturb its delicate sensors.

  • Power module (with voltage and current sensing)
  • I2C splitter (supporting AUAV, Hobbyking and 3DR peripherals)
  • Cable kit for all common peripherals

Wifi (no USB required)

One of the main features of the board is its ability to use Wifi for flashing new firmware, system setup and in-flight telemetry. This frees it of the need of any desktop system.
