New page

For the interconnect between I2C masters and the I2C expansion boards BitWizard uses a 4-pin I2C cable.

{| border=1

|-
| 1 || GND || Power Ground
|-
| 2 || SDA || Serial I2C Data
|-
| 3 || SCK || Serial I2C Clock
|-
| 4 || VCC || Power 5V.

The connector is laid out as follows:

{| border=1

You could use other pins, but then you have to make a software I2C implementation. This is not too difficult, but might be neccesary if something else is already on the I2C pins.
