SparkFun micro:bit Breakout Board

SparkFun Micro Bit Breakout

Micro Bit Breakout (BOB-13988)

The Micro Bit Breakout is a board that connects to the BBC micro:bit and breaks out all 21 GPIO pins, power, and ground to a 0.1" header. It expands the capabilities of the micro:bit by providing access to more pins and allowing for connections to the I2C and SPI buses.

The micro:bit Breakout Board is also available with pre-soldered headers. More information can be found in the Micro Bit Breakout Hookup Guide.
