www.kitronik.co.uk/5601B
Introduction:
This breakout board has been designed to offer an easy way to
connect additional circuits and hardware to the edge connector on the BBC
micro:bit. This edge connector offers access to a large number of the BBC
micro:bit processor pins. For details on these please refer to the next page.
To use the breakout board the BBC micro:bit should be inserted firmly into the
connector as shown below.
Layout:
BBC micro:bit compatible connector
Solder pads connected to the BBC
micro:bit I2C pins
Examples of board in use:
This breakout board is used in our ‘Inventors kit for
