Offers demo-ready compatibility with popular kits like the SO-ARM101 Low-Cost AI Arm—ideal for AI vision projects and educational prototyping. Open-Source for Custom Development： Full Arduino IDE support enables bespoke motion programming, while the 3D-printed enclosure is open source, providing a starting point to customize your casing design. Specification Parameter Description MCU XIAO ESP32-C3 Input Voltage Range 5-12V DC (dependent on servo voltage) Communication Protocol Serial bus protocol (compatible with ST/SC servos) Compatible Servo Types ST/SC series serial bus servos Servo Control Quantity Multiple Control Interface UART / USB Power Supply Interface 2P 3.5mm screw terminal Servo Interface 3P 2.5mm terminal Dimensions 42mm x 25mm Weight 15g Operating Temperature 10°C ~ 60°C FAQs Q: How do I power the Bus Servo Driver Board? A: Connect the power supply via the onboard 2P 3.5mm screw terminal. The input voltage range is 5-12V DC, which must match the rated voltage of the servos used and provide sufficient current to support all connected servos during operation. Q: How do I connect servos and control devices to the board? A: Servos are connected to the driver board via the 2.5mm 3P terminal, ensuring proper wiring (power, ground, signal lines). Control devices can be connected to a computer via the USB interface or to a microcontroller via the UART interface, with the specific mode determined by the jumper settings. Q: How many servos can this driver board control? A: It can control multiple ST/SC series serial bus servos, with the exact number depending on the power supply capacity and bus load conditions. Theoretically, it supports a large number of servos working together.
