Edge Connector Breakout Board for the BBC micro:bit
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
BBC micro:bit’. This kit is supplied with instructions detailing a number of uses
for the board. These can be found at
www.kitronik.co.uk/microbitinvent
Pin headers connected through to the
BBC micro:bit pin numbers as
indicated
This area is fitted with a 20x2 row of
pin headers. These can be used to
connect an IDC cable or jumper wires.
Prototyping area
This area has been designed to allow
you to prototype small circuits. There
is a 3V and 0V row, and three
additional connecting sections.
