Tim's Servo Tester

The PCB from PCBWay was just as I had designed it. In this project I am using an STM8S103F Microcontroller in a TSSOP-20 Package, these have very small pins and quality of the PCB make fitting these packages easy. My project is a tool to test the ranges of small RC Servos. Modern Digital Servo have more permitters to check, this tool enables you to check all the parameters you need to know of a small Servo. 🔧 Why I Built My Own Tester My tester allows: Pulse width adjustment from 0.4ms to 2.6ms Fine control in 0.01ms steps, and 1µs precision when holding a button — perfect for measuring deadband Selectable frequencies: 50Hz, 100Hz, 150Hz, 200Hz, 250Hz, 300Hz Live square wave display, showing Pulse Width, Period, and expected Angle
