Hiwonder 6 Channel Digital Servo Tester with Over-Current Protection

The Hiwonder 6 Channel Digital Servo Tester with Over-Current Protection is a highly practical tool designed for simultaneously testing and calibrating up to six servos. It is ideal for South African makers, students, and robotics hobbyists who want to streamline their hardware setup without writing code first. This compact board is perfect for verifying movement ranges, aligning servo horns, and debugging multi-axis systems.

Dual power supply options

This tester supports two power supply methods, giving you the flexibility to power your setup according to your workbench or portable project needs.

Clear board layout and parameters

The board features a clearly labelled layout for quick connections and safe operation during testing. Its compact parameters make it an easy fit for any electronics workstation.

Real-time manual potentiometer control

You can control the rotational angle of all six servos in real time using the high-precision onboard potentiometers. This provides immediate physical feedback to help you test ranges of motion.

Instant one-button centre reset

A dedicated reset button instantly returns all six servos to their neutral centre position of 90 degrees. This is essential for accurately mounting servo horns and calibrating linkages.

Integrated over-current protection

To protect your valuable components from damage, servo interfaces 0, 1, and 2 are equipped with built-in over-current protection. This safeguards your system against excessive current draw during high-load testing.

Simplified robotic arm debugging

Test multi-joint robotic arms by controlling each servo channel individually. This allows you to verify physical clearances and joint limits before deploying your control code.

Efficient robotic claw calibration

Fine-tune the gripping limits of robotic claws and end-effectors. The manual adjustment knobs let you find the precise open and closed positions without risking motor stall.

Multi-axis servo gimbal testing

Calibrate pan-and-tilt camera gimbals quickly by adjusting the corresponding channels. This ensures smooth, coordinated movement across all axes before final assembly.
