This motor driver module is a special PPM signal motor controller for Aero modelling remote control. It is designed by DFRobot and it can be controlled by RC transmitter. The driver can convert PPM signal to the motor speed and direction control signal. There are two signal receiving channels (CH1, CH2) and two motor channels (M1, M2) on the board. Each signal input channel uses a standard 50-Hz PPM signal with a duty cycle of 5% to 10%. When the rocker returns to the middle, the motor stops rotating, waggling the rocker up and down (or left and right), and the motor rotates forward or backward.
The motor driver supports 7 ~ 12V wide range power input, the maximum input voltage is 40V, and the continuous current of each channel is 3A, the allowable peak current is 6A. When the current is over 6A, the driver chip will be into a protected state (in the protection state, it requires repower to start again). The module has LDO power management system, which can provide an output current of 5V/200mA externally. Therefore, the remote control receiver of the model can be directly connected to the driver board without additional power supply to the receiver.

Jargon buster
Plain-language definitions for the technical terms used above.
- duty cycle
- The fraction of time a signal or light source is switched on during a repeating cycle. On a proximity sensor, changing the duty cycle can affect detection range, response speed, accuracy and power use.
- motor driver
- An electronic circuit that lets a low-power controller switch and control a motor that needs more current than the controller pins can safely provide. Checking motor driver support matters because pumps and motors usually cannot be connected directly to a microcontroller output.
- ppm
- ppm means parts per million, a common way to express very small gas concentrations in air. For CO₂ sensors, the ppm range tells you what levels the sensor can measure, such as normal indoor air through to poorly ventilated spaces.
- servo
- A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
