max GPIO sink current on nrf51822

[Bryan Hood]

How 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? Thanks

Hi Bryan,

Same applies for current sink, maximum 3 pins at 5mA. However, if you have only one pin sinking, you can sink upto 15mA on that single pin.
