ESCs & Motors

Many PX4 drones use brushless motors that are driven by the flight controller via an Electronic Speed Controller (ESC). The ESC takes a signal from the flight controller and uses it to set control the level of power delivered to the motor.

PX4 supports a number of common protocols for sending the signals to ESCs: PWM ESCs, OneShot ESCs, DShot ESCs, DroneCAN ESCs, PCA9685 ESC (via I2C), and some UART ESCs (from Yuneec).

Supported ESC
