Hiwonder Digital Servo Tester Controller with Voltage Display

The Hiwonder Digital Servo Tester Controller with Voltage Display is a practical tool for quickly testing and calibrating up to two servos simultaneously. Perfect for students, educators, and makers, this controller allows you to debug your robotic builds without writing a single line of code.

Dual power supply interfaces

This tester features two power supply interfaces, providing flexible options for powering your servo testing setup.

Clear product parameters

With clearly defined parameters, this compact board is straightforward to integrate into any electronics workbench or hobbyist toolkit.

Real-time voltage monitoring

The integrated voltage display module lets you monitor the voltage of your power supply equipment in real time. This helps prevent the voltage from dropping too low to safely control and test your connected servos.

Manual potentiometer control

A high-precision potentiometer allows you to manually control the synchronous angular rotation of two servos in real time. This is ideal for testing range of motion and checking for mechanical interference.

Quick return to centre

Reset the angle of your two-way servos back to the 90-degree centre position instantly with the onboard reset button. This simplifies the process of centering your servos before final mechanical assembly.

Robotic arm calibration

Easily debug and calibrate the joints of your robotic arms during assembly to ensure accurate physical alignment.

Robotic claw testing

Fine-tune the gripping limits and movement of robotic claws and end effectors before connecting them to your main microcontrollers.

Servo gimbal alignment

Test and align pan-and-tilt servo gimbals quickly to ensure smooth movement across both axes of rotation.
