The BBC micro:bit is a pocket-sized microcontroller designed to facilitate computer education and physical computing through an accessible hardware interface. This category encompasses a comprehensive ecosystem of peripherals developed to extend the board's capabilities, prominently featuring the Maqueen robotics series for STEM applications, alongside diverse IO expansion boards, gamepads, and IoT connectivity modules. These accessories enable the integration of complex sensors and actuators into micro:bit projects. This Wiki serves as a central resource for technical documentation, offering detailed connection guides, programming tutorials (supporting MakeCode、Mind+ and Python), and hardware specifications for the full range of DFRobot micro:bit compatible devices.
