https://devzone.nordicsemi.com/f/nordic-q-a/996/max-gpio-sink-current-on-nrf51822How much current can the nrf51822 sink per pin? In the datasheet, I can see that it is at least 5mA. I also see that the chip can drive 3 pins at 5mA, but can it handle more as a current sink?

However, if you have only one pin sinking, you can sink upto 15mA on that single pin.</p><div style="clear:both;"></div>
