his 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:

  1. Allows controlling up to 253 ST/RSBL series serial bus servos at the same time.
  2. 9~25V wide voltage input (the input voltage and the servo voltage must be matched).
  3. Based on the ESP32-WROOM-32 module, supports wired and wireless communication.
  4. Provides multiple control demos for different host controllers.
  5. Supports controlling the serial bus servos directly via onboard USB Type-C port.
  6. 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

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
