Servo Driver Board with ESP32 for Raspberry Pi 4B/5, Waveshare Serial Bus Design

The Servo Driver Board with ESP32 is designed for advanced robotics and automation projects, specifically for use with Raspberry Pi 4B and 5. It integrates an ESP32-WROOM-32 module, allowing for both wired and wireless control of up to 253 serial bus servos. This board is ideal for users working on complex robotic systems that require precise control and real-time feedback from multiple servos.

The board supports a wide range of input voltages from 9 to 25V, making it adaptable to various power sources. It is compatible with ST and RSBL series serial bus servos, ensuring a broad range of applications. The ESP32 module provides built-in WiFi and Bluetooth capabilities, enabling wireless communication and remote control options. This makes it suitable for projects that require mobility or remote operation.

The board features a neat cable management system, allowing it to power the Raspberry Pi through an integrated 5V buck regulator circuit while communicating via the GPIO UART interface. It also includes a USB Type-C port for direct control of the servos, eliminating the need for additional controllers. The board comes with multiple control demos and Python scripts, simplifying the setup and development process for users.

This driver board is particularly useful in robotics projects such as quadruped robots, hexapod walkers, and robotic arms. It allows for advanced control with features like position, speed, torque lock, and operating mode feedback from the servos. The ability to send and receive JSON commands makes it easier to integrate into larger systems or custom applications.
