Which nRF52840 registers can be deactivated to achieve lowest power possible?https://devzone.nordicsemi.com/f/nordic-q-a/64421/which-nrf52840-registers-can-be-deactivated-to-achieve-lowest-power-possibleHello everyone, I am developing a simple BLE node with an I2C sensor on it. Basically I just need to send over BLE the measurements made by that I2C sensor every minute or so. Fortunately, I managed to make it work using the arduino nano 33 BLE boarden-USTelligent Community 13Mon, 03 Aug 2020 12:09:56 GMTRE: Which nRF52840 registers can be deactivated to achieve lowest power possible?https://devzone.nordicsemi.com/thread/262780?ContentTypeID=1Mon, 03 Aug 2020 12:09:56 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5af1f963-7edd-4e77-8ab8-5cc74da78c4fVidar Berg<p>Hello,</p> <p>Do you know if the UARTE interface may be enabled in your project? Maybe it&#39;s used for logging? This is one of the peripherals that has to remain active in idle mode and thus increases idle current (usually around ~1mA). The total current would have been much higher if the chip didn&#39;t enter sleep at all. Most peripherals such as TWI powers down automatically.</p> <p>Note that you can use our online power profiler to find the expected current consumption for a given configuration:&nbsp;<a href="https://devzone.nordicsemi.com/nordic/power/w/opp">https://devzone.nordicsemi.com/nordic/power/w/opp</a>&nbsp;</p> <p>Best regards,</p> <p>Vidar</p> <p></p><div style="clear:both;"></div>
