AWuAV 3015E the Revolutionary Open Source drone

The Pixracer is the first autopilot of the new FMUv4 Pixhawk generation. It has Wifi built-in, comes with upgraded sensors and more flash. The final revision of this new design will likely consolidate on a single set of sensors (either ICM or MPU, both from Invensense).

  • Integrated Wifi telemetry and boot loading through ESP8266 (config and firmware)
  • Invensense ICM-20608 Accel / Gyro (4 KHz)
  • Invensense MPU9250 Accel / Gyro / Mag (4 KHz)
  • Honeywell HMC5983 magnetometer with temperature compensation
  • Measurement Specialties MS5611 barometer
  • JST GH connectors
  • microSD
  • Futaba S.BUS and S.BUS2 / Spektrum DSM2 and DSMX / Graupner SUMD / PPM input / Yuneec ST24
  • FrSky telemetry port
  • OneShot PWM out (configurable)

Connectors / Pinout

All connectors follow the Dronecode connector standard. Unless noted otherwise all connectors are JST GH.

Main interfaces:

  • GPS (serial + I2C)
  • TELEM1
  • TELEM2
  • Wifi serial
  • FrSky Telemetry serial
  • Dronecode Debug connector (serial + SWD)
