This open-source servo controller utilizes a modular master control architecture, allowing for flexible switching between ESP32 master controllers via the onboard MCU master controller dock. The controller integrates a dual-mode servo driver engine, making it compatible with Huaner's 5-8.4V full-bus servos and PWM servos, as well as mainstream servos on the market. It features a built-in Bluetooth communication module and offers multi-modal expansion interfaces such as a USB controller, IIC GPIO, and serial ports. It also includes programmable custom buttons, a buzzer, and other electronic modules, allowing for expansion of peripherals such as vision modules and AI voice interaction modules. This provides a highly flexible solution for development and expansion, making it an excellent choice for robotics projects!
