A plug-and-play servo testing controller designed for quick and precise PWM servo debugging. With three control modes, dual power options, and built-in current protection, this compact board is ideal for robotics, RC models, and DIY electronics. No programming required—just connect and test instantly.

Key Features & Benefits

Feature Benefit & Explanation
Three Control Modes Supports Manual (knob-based control), Center (auto-reset to 90°), and Sweep (automatic 0°–180° rotation)—perfect for diverse testing needs.
Wide Voltage & Dual Power Supply Compatible with 5V to 8.4V input. Choose between Micro USB (5V) or KF301 terminal (6–8.4V) power for flexible operation. (Note: Do not use both power inputs simultaneously.)
High Precision, No Programming Needed Equipped with the STC8G1K08A microcontroller, generating accurate PWM signals with 0.09° precision. Works right out of the box—no coding required.
Current Protection Circuit Integrated over-current protection (>1A) keeps your servo and tester safe during operation.
Dual Servo Output Ports Two 3-pin servo ports allow simultaneous testing of two servos for greater efficiency.
Versatile Applications Ideal for robot arms, mechanical grippers, RC vehicles, AI robotics, and DIY prototypes needing precise servo control.
