micro: Breadboard Brand_CamdenBoss and also on our Arduino-compatibleMicro: breadboard is an expansion board for the BBC micro: bit, specially designed for STEM. It comes with a 3. 23x2. 17 breadboard (independent packing, you need to stick them together), on which you can directly build circuits with all sorts of electronic components. All IO ports are broken out in the form of pin headers and female headers, so no soldering is required. The electronic parts can be used repeatedly, which greatly reduces circuit
