This Edge Connector Breakout Board for the BBC micro:bit gives access to all of the important pins on the bottom edge of the BBC micro:bit. 21 pins are broken out in total; providing additional I/O lines, direct access to buttons A and B, the LED matrix outputs and the I2C bus.
The BBC micro:bit pins are broken out to a row of pin headers. These provide an easy way of connecting circuits using jumper wires. The SCL and SDA pins are separated at the edge of the board (solder pads) providing easy identification. The PCB includes a prototyping area with 3V, 0V and unconnected rows that can be soldered to. This allows the easy connection of switches, sensors and any pull-up or pull-down resistors etc. as required.
