Build Your Autonomous Car!

RC Driver HAT is a Raspberry Pi interface board for making autonomous RC vehicles. You can control ESCs, servo motors, LED lighting; connect sensors, decode receiver pulses, and much more to digitize your RC vehicle. It combines everything needed for controlling RC vehicles using Python!


  • The board takes control of your RC car via its 4Ch PWM output. It's compatible with most ESCs and RC servos.
  • With RC Driver HAT's 4Ch analog inputs, your car detects its surroindings if you connect distance sensors to it.
  • Connect RC remote controller via 4Ch PWM decoder for manual control.
  • Decorate your RC car with LEDs using RC Driver HAT's 5Ch MOSFETs.
  • Maintain 3D orientation and measure the 3D acceleration of your car using the on-board IMU.
  • Measure speed and wheel RPM of your car using 2Ch tachometer inputs.
  • Raspberry Pi can become hot while dealing with image processing. Cool it down with the onboard fan.
  • Power your Raspberry Pi with 2 to 6 Cell Li-Po or equivalent battery. RC Driver HAT monitors the battery Voltage. Its high-efficiency switching power supply uses a minimum amount of battery.
  • Connect external sensors, displays, or GPS using Grove System compatible I2C and UART ports.
  • The board carries ID EEPROM for Raspberry Pi HAT specification compliance.


RC Driver HAT comes with rich documentation located at docs.turta.io/raspberry-pi-hats/rc-driver-hat address.
