Nrf51 4uA sleep current

[carlche]

Hi guys,

I’ve got a simple nrf51822 board which does not have any GPIO used - the system is a beacon doing its own advertisement without any intervention. The board schematic is very standard nrf51822 one. The advertising works well however the sleep current I measured is 4uA ish rather than 2.7uA (using 3V power supply). Is there anything wrong here? Can you please point out which area I need to check for this issue?

Thanks,

Carl

Hi Carl

Please check out the nRF51 current consumption guide, which touches upon nearly every way to reduce current consumption.

Best regards,
