Description:
This is a driver board specifically designed for serial bus servos, integrating an ESP32 and serial bus servo control circuits. It features onboard RS485 and TTL serial bus servo interfaces. We have open-sourced the serial bus servo control demos and JSON communication interface. Users can connect via USB and use a host computer to send JSON formatted commands to control the serial bus servos and receive JSON formatted feedback (such as servo torque, speed, position, etc.).
Users can also perform secondary development on it, using it as a slave controller in their robotics projects.
Feature:
- Allows controlling up to 253 ST/RSBL series serial bus servos at the same time.
- 9~25V wide voltage input (the input voltage and the servo voltage must be matched).
- Based on the ESP32-WROOM-32 module, supports wired and wireless communication.
- Provides multiple control demos for different host controllers.
- Supports controlling the serial bus servos directly via onboard USB Type-C port.
- Supports connecting to Raspberry Pi, powering the Pi via integrated 5V buck regulator circuit and communicating through GPIO UART interface, neat cable management.
Package Includes:
1 x Bus Servo Driver HAT (A)
1 x 2×20 pin header
1 x USB-A to USB-C cable
1 x Screws pack
