Servo tester 3 channels 3 modes servo driver CCPM MG995 MG996r S3003 SG90

3-channel servo tester and driver for Arduino and Raspberry Pi Professional servo tester, also usable as an ESC test signal generator. The device works with popular servo models such as SG90, MG996, MG995, S3003, and many others. The module is ideal for projects using microcontrollers, including Arduino, ESP32, ESP8266, and Raspberry Pi. Key technical specifications

* Operating voltage: 4.8 - 6 V * Output signal: 1.5 ms ± 0.5 ms * Servo support: ability to connect up to 3 servos at once * Compatibility: can connect ESC speed controllers * Dimensions: 35 x 32 x 30 mm Three operating modes The tester offers three modes for thorough testing of connected components:

* Manual - by turning the knob, you can check the response time of several connected servos. * Neutral - servos move to their neutral (centre) position. * Automatic - also known as wiper mode - servos sweep across their maximum rotation angle. Example applications

* Testing servo condition and range of motion. * Generating a signal to verify ESC operation. * Setting servos to centre position before mounting in a mechanical assembly. * Checking response time of several servos simultaneously. * Diagnosing servo motion smoothness in automatic mode. Benefits

* Quick testing of up to 3 servos at the same time. * Simple verification without programming a microcontroller. * Three built-in modes for different kinds of tests. * Compact size for easy handling and storage. * Broad compatibility with popular servo models.
