https://devzone.nordicsemi.com/f/nordic-q-a/16596/spi-master-high-current-consumption-once-enabled-disabledI&#39;ve got a custom NRF52 board that uses less than 4uA when sleeping without SPI but after the SPI is initialized (and then uninitialized) the current consumption rises to 2mA during sleep. I&#39;ve reduced my code to this: nrf_drv_spi_init(&amp;spi_instanceen-USTelligent Community 13Thu, 05 Jan 2017 22:27:44 GMThttps://devzone.nordicsemi.com/thread/63487?ContentTypeID=1Thu, 05 Jan 2017 22:27:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6c6e0506-7c5f-4a91-8ad6-95f19bea2bcckmorris<p>Hi Brian - Did you ever figure this out? I think I&#39;m seeing something similar... though mine is closer to 5mA.</p><div style="clear:both;"></div>
