Overview

• ESP32 Servo Drive Expansion Board
• Driver board specially designed for bus servos
• It can control up to 253 servos through the ESP32 serial port, open source the bottom layer and web applications, and open source the hexapod and humanoid robot structure, which can be used as the main control board for building robot projects. 

Features

• Can control up to 253 SC, ST series bus servos at the same time (provided that the power supply is sufficient)
• Wide voltage input 6-12V (input voltage needs to match the servo voltage)
• Built-in WIFI and Bluetooth, support ESP-NOW, can remotely control and debug the servo
• Automatic download circuit is convenient for uploading programs
• Open sourced web applications and various robot structures
• Mini and compact, save space, suitable for embedding into various projects with high space requirements

Specifications

• Supply voltage: DC 6-12V
• Power supply interface: 5.5 × 2.1mm DC
• Download interface: Type-C
• Main control chip: ESP32
• Control mode: UART
• Product size: 30 × 65mm
• Via diameter: 2.75mm
• Positioning hole spacing: 23 × 58mm

Main usage indication

• The servo can feed back a variety of information: position, speed, torque lock, operating mode (servo mode, servo motor mode, etc.) can be used for advanced projects that require closed-loop automatic control
• Can be used to build quadrupeds, hexapods, robotic arms and other robotic projects that require multiple steering gears

The picture here is for reference only.

Using serial bus control

• Can control up to 253 SC, ST series bus servos at the same time

Note: One UART can control 253 bus servos, but due to the high power of the servos, it is necessary to consider whether the power supply scheme can meet the requirements when using too many servos 

Applicable steering gear products

This product does not contain SC15 Servo and ST3215 Servo.

Please purchase separately if necessary.

Wide voltage input 6 ~ 12V

• The input voltage needs to match the servo voltage

Note: The input voltage must match the servo voltage. For example, when using the servo SC15 Servo with a voltage of 6-8.4V, the input voltage of the DC port of the driver board should also be within the same range of 6-8.4V. 

ESP32 master control, rich data

• Convenient for secondary development
• Built-in WIFI and Bluetooth, support ESP-NOW at the same time, can remotely control and debug the servo

OLED screen status display

WIFI remote control

• The driver board has built-in WIFI and Bluetooth, and supports ESP-NOW, which can remotely control and debug the servo
