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), etc., 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 such as robotic arms, hexapod robots, humanoid robots, wheeled robots, etc. that require feedback on the angle and load of the steering gear.

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

Applications

• Servos will provide various feedback like position, speed, torque lock, 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

Allows Controlling Up To 253 SC, ST Series Serial Bus Servos At The Same Time

Note: Though One Channel UART Is Able To Control Up To 253 Bus Servos, Due To The High Power Of The Servos, It Is Necessary To Consider Whether The Power Supply Solution Is Enough When Using Too Many Servos.

The Input Voltage And The Servo Voltage Must Be Matched

T

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