Waveshare ESP32-Powered Servo Driver Expansion Board With Integrated WiFi & Bluetooth Connectivity For Robotics and IoT Projects - RS8446

Description:

This product is a bus servo control board based on ESP32 and we provide examples that can control bus servos through the WEB application. This product supports the programming of servos to change the ID and working mode of the servos (servo mode/motor mode) in theory, it can control 253 bus servos and read the current angle, load, voltage, mode, and other information of each servo, and can use the serial port to communicate with the upper computer, which is used to build the lower computer of the robot project, and the on-board OLED.

The screen can be used to display key information and is suitable for robot projects that require feedback on the angle and load of the servos such as robotic arms, hexapod robots, humanoid robots, wheeled robots, etc.

Specifications:

• Supply voltage: DC 6-12V(the input voltage and the servo voltage must be matched)
• Controller: ESP32
• Control interface: UART
• Download interface: Type-C
• Power supply connector: 5.5*2.1mm DC
  
• Fixing hole diameter: 3.0mm
• Mounting hole size: 2.75mm

Features:

• Allows controlling up to 253 SC, ST series serial bus servos at the same time (adequate power supply required).
• Wide range voltage input 6-12V (the input voltage and the servo voltage must be matched).
• Built-in WiFi and Bluetooth, as well as ESP-NOW support, for remote control and servo debugging.
• Automatic download circuit for easy uploading programs.
• Open-source web applications and various robot structures.
• Compact size and space-saving, suitable for integration into sorts of space-limited projects

Application Examples:

• Servos will provide various feedback like position, speed, torque lock, and operating mode (servo mode, servo motor mode, etc.) for advanced projects requiring closed-loop automatic control
• An Ideal choice for building quadruped robots, hexapod walkers, robotic arms, and other robotic projects requiring multiple servos
