micro:bit Expansion Board for Boson (Gravity Compatible)

micro:bit Expansion Board for Boson (Gravity Compatible) Overview

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 themicro:bitExpansion Board for Boson, a carry-on board that connects to micro:bit via the edge connector.

The expansion board comes with 6 fool-proof 3-Pin sockets, compatible with hundreds of DFRobot’sBosonandGravitymodularized electronic blocks, covering most populardigitalandanalogsensors and actuators, supporting sound, light, and motion interaction.

Moreover, the expansion board adds aGravity: HuskyLensinterface and an IIC interface. To ensure a steady current supply for these peripherals, the expansion board can be powered externally through the Micro-USB power port.
