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

Equip your micro:bit with this 4-DOF metal robot arm and get started to explore the world of Artificial Intelligent robotics.

This starter robotic arm kit includes a servo driver board, metal mechanical arm structure and 4 metal gear servos. When used with the micro:bit, it's easy to control the arm by smart phone through a Bluetooth connection.

This arm is compatible with the micro:bit V1 and the micro:bit V2.

Servo Driver Features

• micro:bit edge connector, directly pluggable
• I2C controlled, using only 2 pins
• Up to 16-Channel servo/PWM outputs, 12-bit resolution for each channel (4096 scales)
• Integrates 5V regulator, up to 3A output current, can be powered from battery through VIN terminal
• Standard servo interface, supports common used servo such as SG90, MG90S, MG996R, etc.
• Reserved I2C control pins, allows to work with other control boards
• Comes with development resources and manual (micro:bit graphical examples like Bluetooth/2.4G wireless remote control)
