This is a Waveshare ESP32 Servo Driver Expansion Board Built-In Wi-Fi and Bluetooth.

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 ESP32 Servo Driver Expansion Board supports 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.
