4-DOF Metal Robot Arm Kit for micro:bit - Bluetooth version

The Waveshare 4-DOF Metal Robot Arm Kit is a comprehensive starter package designed for the BBC micro:bit. It features a robust aluminum alloy construction with four degrees of freedom, allowing for versatile movement and manipulation. The kit includes a servo driver board that connects directly to the micro:bit via its edge connector, facilitating easy setup without soldering. Communication is handled through I2C, utilizing only two pins, and the system supports up to 16-channel servo/PWM outputs with 12-bit resolution per channel. The integrated 5V regulator can supply up to 3A, powering multiple servos efficiently. Control the arm wirelessly using a smartphone via Bluetooth, making it ideal for educational purposes, prototyping, and exploring robotics.
