Looking to do more with your BBC micro:bit? Unlock its potential with this Edge Connector Breakout Board! This breakout board has been designed to offer an easy way to connect additional circuits and hardware to the pins on the edge of the BBC micro:bit. It provides access to all of the BBC micro:bit processor pins allowing a lot of extra functionality to be added. The datasheet (below) includes a helpful diagram explaining the function of every pin on the BBC micro:bit.
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. Please refer to the datasheet below for more details.
The BBC micro:bit pins are broken out to a row of solderable pads. The SCL and SDA pins are separated at the edge of the board 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.
If you are looking for inspiration, look no further than these examples using the Edge Connector for the BBC micro:bit:
- The breakout board is used in our Collision Detection Buggy that makes use of the extra I/O available.
- We've also used this Edge Connector for the BBC micro:bit in our Inventor's Kit for the BBC micro:bit to make connecting up these experiments a breeze.
To use the breakout board the BBC micro:bit should be inserted firmly into the connector as shown below:
- This kit requires assembly.
- This kit requires soldering.
- This product is also available in a pre-built version.
- Breaks out 21 pins from the Edge Connector for the BBC micro:bit, allowing the connection of extra components to add new functionality.
- Dedicated prototyping area with 3V and 0V rows.
- Labelled pins and clear straightforward documentation.
- 1 x Edge Connector PCB for the BBC micro:bit.
- 1 x Edge Connector for the BBC micro:bit.
Possible applications include:
- Accessing additional pins and functionality on the BBC micro:bit.
- Trying out one of the experiments detailed in the Inventors kit for BBC micro:bit.
- Length: 60mm.
- Width: 40mm.
- Height: 11.8mm.
Worth pointing out that the graphic in the middle of this page (how to plug the micro:bit into the breakout board) implies that pin 9 is not brought through to the header pins where in reality it is, as per the photo at the top of the page.

Firstly thank you for pointing this out, we were aware of this error and we are in the process of changing the diagram shown on the product page. We hope to update this shortly.
Hi there, Where Do I find the schematics of the micro:bit? (I need to know which pins connect to each output), thanks

The following datasheet shows what pins on the BBC micro:bit relate to the pin on the breakout board via a number, you need to look at page 2 https://www.kitronik.co.uk/pdf/5601_edge_connector_breakout_board_for_the_bbc_microbit_datasheet_1_0.pdf
There's something of a loose fit between the connector and the board, is it expected that I should solder the 80 pins into place (or at least the ones I need)?

We would always advise that all the pins are soldered together, however as a minimum we would recommend that the first two rows are completely soldering, and then a selection from the back row are also soldered in.
Hi, I've just ordered this item. Are there dimensions and hole placement mounting instructions available please? Thanks.

We are currently in the process of uploading an image which shows the dimensions of the product. However in the meantime I have emailed a copy to you.
Why is it an 80 way connector? I understood that there were about 25 lines coming out to the edge of the board and all the pictures seem to confirm this. Are there separate lines on each side of the board, which if there were would still only bring it up to 50.

The connector itself has 80 pins, the BBC micro:bit that it is designed to fit only uses 40 pins, of those only 22 or so are broken out as not all of the pins have functions we expect people to want to use.
