This is a low-cost expansion board for Micro:Bit, which is specifically used for easy access of the IO ports on the Micro:Bit. It breaks out all the IO contacts on the Micro:Bit and comes with a built-in buzzer. The buzzer is connected to the P0 pin through the slide switch. The small size is very suitable for small projects using Micro:Bit.
Small size, very suitable for DIY; All IO ports are extracted; Two LEGO-compatible pin holes for easy assembly and integration; Includes 1A self-recovery fuse; Custom-designed silkscreen board On-board buzzer- you can directly use the music module in MakeCode to play music. At the same time, the 3.5mm audio connector on the board can be connected to audio equipment; such as headphones to have more creative endeavors The 3PIN interface is distinguished by yellow, red, and black. It is created so that plugging it in the wrong way is difficult, and it is convenient to plug in the sensors Compared with IObit1.0, the biggest difference is that it can input and output 5V, support 5V sensor use, and increases the drive capacity (can drive multiple 9g small servos) It imitates the 5PIN gold fingers on the Micro: bit. This is convenient for makers who like to use the alligator clips; Come with a 2 Section Battery Holder for power micro: bit.
