DF Robot Light & Motor Driver for Python

The DF Robot Light & Motor Driver for Python is a versatile, high-current PWM driver board designed for precise control of DC motors and LED lighting systems. Supporting four independent control methods—Python programming, PC software control, UART communication, and manual potentiometer adjustment—it offers exceptional flexibility for both development and deployment scenarios. With a wide 5V–24V input range and up to 10A load capacity, it can reliably drive DC motors up to approximately 50W or LED strip lights up to 5 meters in length.



Ideal for automation, testing, and retrofitting projects, this driver board enables seamless integration with computers, embedded systems, and development platforms such as Raspberry Pi, LattePanda, and industrial PCs. The use of a high-current MOSFET design ensures stable PWM output, while support for the standard MODBUS protocol allows advanced users to implement custom control systems. Whether used for automated fan control, lighting effects, water pump regulation, or power tool modification, this module delivers robust performance with minimal setup complexity.
