擴展板帶有6個防呆的3-pin插座，與數百個DFRobot的 Boson 和 Gravity 模組化電子模組相容，覆蓋了大多數流行的數位和類比感測器和外部模組，支持聲音，光線和互動模組。
micro:bit is a pocket-sized microcontroller designed for kids and beginners to learn coding and electronics, letting them easily bring ideas into DIY digital games, interactive projects and robotics.
However, on-board I/O rings and crocodile clips sometimes are not handy and safe enough to connect peripherals. To explore more possibilities with micro:bit, we have designed the micro:bit Expansion Board for Boson, a carry-on board that connects to micro:bit via edge connector.
The expansion board comes with 6 fool-proof 3-Pin sockets, compatible with hundreds of DFRobot’s Boson and Gravitymodularized electronic blocks, covering most popular digital and analog sensors and actuators, supporting sound, light and motion interaction.
Moreover, the on-board 3.5MM headphone jack and volume knob supports direct connection of headphone.
To ensure a steady current supply for these peripherals, the expansion board can be powered externally through the USB power port.
