# i2c2
2+
3+
```package
4+
pins=github:bsiever/microbit-pxt-i2cpins
5+
```
6+
7+
This extension allows non-default pins to be used for the micro:bit's I2C
8+
9+
**Micro:bit v1 only has one I2C port. Changing the pins will prevent the accelerometer/compass from working!!!**
10+
11+
# Setting the pins
12+
13+
```sig
14+
pins.setI2CPins(sda : DigitalPin, scl : DigitalPin) : void
15+
```
16+
17+
Set the Data and Clock pins.

Development of this extension was sponsored by [MakeKit](https://www.makekit.no/).
