https://devzone.nordicsemi.com/f/nordic-q-a/17710/eval-adxl345z-and-mb39c811-evbsk-02Hi, I&#39;m new and I&#39;m a student. I have to connect the adxl345z to my board mb39c811-evbsk-02. It has an nrf51822 integrated. Someone can explain which pin of i2c/Gpio i have to use?

Not sure how easy is to connect to it on PCB.</p><div style="clear:both;"></div>
