Description
The ToolkitRC ST8 Advanced Servo Tester is a professional-grade, multi-functional testing and measurement tool designed for RC hobbyists, drone builders, and robotics engineers. Featuring a wide DC input voltage range (7.0V to 28.0V) and capable of handling up to 10A, the ST8 serves as a robust servo tester, signal generator, and power meter. It supports multiple signal protocols including PWM (500us–2500us), 8-channel PPM, and 16-channel SBUS with adjustable signal frequencies ranging from 33Hz to 1000Hz.
Equipped with a crisp 2.4-inch TFT RGB color display (320×240 resolution), the ST8 provides real-time monitoring of voltage, current, signal width, and frequency. With adjustable output voltage (5.0V to 8.4V at up to 4A) across multiple signal ports (S1-S4), it allows users to precisely test servos, measure power consumption, and analyze radio control signals. A built-in USB micro port allows for quick firmware upgrades, making it an essential, highly portable addition to any workbench or field kit.
