PPM 2x3A DC Motor Driver

PPM 2x3A DC Motor Driver is a dedicated motor control board designed for aeromodelling platforms and remote control-based robotic systems. This dual‑channel RC motor controller converts standard PPM signals from an RC receiver into precise motor speed and direction control for two DC motors. Two signal input channels (CH1 and CH2) correspond to two motor outputs (M1 and M2), enabling independent bidirectional drive. With support for common 50Hz PPM control signals and wide input voltage compatibility, the compact driver board serves as a reliable control interface between RC transmitters and robotic or model‑vehicle propulsion systems.

Direct PPM Signal Motor Control

This RC motor driver board interprets standard 50Hz PPM servo signals with a 5–10% duty cycle, translating joystick movement into forward, stop, or reverse motor behavior. A centered transmitter stick places the motor in a stop state, while directional movement increases speed in either direction. Such signal compatibility allows seamless integration with common RC receivers used in aircraft models, ground vehicles, and competitive robotics platforms without requiring additional signal conversion hardware.

Dual Independent 3A Motor Channels

The embedded TLE5205 driver architecture enables two independent DC motor outputs, each supporting continuous current up to 3A with peak protection at 6A. Separate signal inputs allow independent control of each motor channel, supporting differential drive robots, tracked vehicles, and propulsion systems requiring precise steering control. Built‑in overcurrent protection automatically safeguards the driver circuitry when load current exceeds safe limits, preventing hardware damage during demanding mechanical loads.

Integrated 5V Receiver Power Output

An onboard LDO power management system provides a regulated 5V output with up to 200mA current capacity. This integrated BEC‑style supply allows a model receiver to be powered directly from the motor driver board, eliminating the need for a separate receiver battery or regulator module. Simplified wiring reduces system complexity and improves reliability in compact robotics platforms and aeromodelling builds.

Wide Voltage Operation with Protection

This dual‑motor control module operates from a recommended 7–12V supply while tolerating input voltages up to 40V. Such flexibility allows compatibility with a variety of battery packs commonly used in robotics and model vehicles. Protective circuitry monitors current levels and automatically enters protection mode when peak current exceeds 6A, helping maintain stable operation during sudden load spikes or stall conditions.

Typical applications include RC model vehicles, aeromodelling propulsion control, small combat robots, tracked robotic platforms, and other remote‑controlled mechanical systems requiring compact dual‑motor drive. The combination of PPM signal compatibility, onboard receiver power output, and dual 3A motor channels makes this controller suitable for hobby robotics, prototyping platforms, and experimental RC mechanisms.
