The 32 Channel Servo Controller Board is a professional multi-servo controller designed for robotics, automation and educational applications. It allows a single microcontroller or computer to control up to 32 servo motors using only one UART interface, significantly reducing GPIO usage while providing accurate and synchronized servo movement.

Built around a 32-bit processor, the controller generates precise 1 µs servo pulses for smooth and stable motion. It is ideal for projects requiring multiple servos operating simultaneously, including humanoid robots, robotic arms, quadruped and hexapod robots, biped robots, animatronics, camera pan-tilt systems and industrial automation prototypes.

The controller communicates through USB Type-C or UART, making it compatible with popular development platforms such as Arduino, ESP32, STM32, Raspberry Pi and PCs. It also supports expansion through Bluetooth, WiFi, and PS2 wireless joystick modules, allowing both wired and wireless control depending on project requirements.

With onboard flash memory capable of storing up to 256 action groups, repetitive movements can be executed directly by the controller without continuously sending commands from the host processor. This reduces processor workload and ensures smooth coordinated motion.

Servo signal isolation improves system reliability by separating servo control signals from the controller circuitry, helping reduce electrical interference generated by multiple high-current servo motors.

Whether you are developing a research robot, educational platform or commercial robotic system, this controller provides a simple and scalable solution for managing large numbers of servo motors.

Why Choose the  32 Channel Servo Controller?

Unlike driving multiple servos directly from a microcontroller, this controller generates accurate PWM signals independently while your main controller focuses on application logic. This improves timing accuracy, reduces processor load, and makes large robotic projects easier to develop and maintain.

Its onboard action group storage also enables complex movement sequences to be executed without continuously transmitting commands, making it suitable for autonomous robotic applications.

Important: This controller supports Bluetooth, WiFi and PS2 wireless joystick control through dedicated expansion modules. These accessories are not included with the controller and must be purchased separately. The controller can be used directly over USB Type-C or UART without these optional modules.
