This prototype breakout board V2 is specifically designed for micro:bit motherboards. It breaks out all the pins from the micro:bit into socket strips, which is very convenient for circuit building. The breakout board features a series of round soldering holes and an external black power socket. You can build your test circuit not only on the easily modifiable 400-point breadboard but also solder directly onto the small universal plate of the breakout board. The breakout board includes a power module that can directly supply power to the micro:bit board and increase the load capacity of the breakout board. The entire design is very easy to use, making it a great choice for adding a circuit prototype.
