Product Description
Preface
This product is a bus servo driver board that integrates servo power supply function and servo control circuit, supports programming the servo to change its ID and operating mode (servo mode/motor mode), etc. Theoretically, it can control 253 bus servos and read information such as the current angle, load, voltage, and mode of each servo. It can be connected to a host computer via a serial port to control the rotation of the bus servos, and is suitable for robot projects such as robotic arms, hexapod robots, humanoid robots, and wheeled robots that require feedback on servo angle and load.

Product Usage
Controlled via UART
For hardware devices without a USB interface, such as Raspberry Pi Zero, ESP32 development board, Arduino development board, STM32 development board, etc., the control and data postback of the bus servo can be achieved by connecting to the hardware device via the UART serial port, and the connection method must be RX-RX, TX-TX corresponding connection.
Here, taking the Raspberry Pi as an example, the basic wiring of the bus servo driver board when using the UART serial port is described. Remove the jumper cap, connect the bus servo to the bus servo interface of the driver board, and use DuPont wires to connect it to the Raspberry Pi via the UART serial port. The power supply voltage of the Raspberry Pi is 5V, which can be input via MicroUSB or GPIO pins; the voltage input of the bus servo driver board must match the power supply voltage of the connected bus servo and can be input via the DC5521 socket.
Note: If you are using SC series servos, you need to use a power supply voltage that matches the SC series servos. The voltage label at the DC power supply interface on the driver board is marked for the power supply voltage of the ST series servos, but in fact, the power supply voltage suitable for the SC series servos can also be input.
