nrf51 Dongle I2C Pin Map

[JoeS]

So after reading some material it seems like I can pretty much define which pins are responsible for I2C communication. Is there any limitation to which pins I can set? Does this work for basically all serial communication the nrf51 series chips are capable of?

@JoeS: No, there is no limitation for digital pins. You can basically configure any GPIO pins as I2C pins.

There is only one note, try not to select the pins close to the radio's pin (ANT1, ANT2) to do high frequency transmission.
