https://devzone.nordicsemi.com/f/nordic-q-a/11103/what-is-the-most-power-that-the-nrf52-can-consume-during-bluetooth-operationHi, Need to know the largest amount of power consumption that the Nordic (nrf52) can consume during the highest power bluetooth mode? Also, what is the largest power consumption of nrf52 at any other state (other than bluetooth)?

Here you can find that the current consumption at 3 V with DCDC enabled is <strong>7.5 mA</strong> with an output power of 4dBm. This is the current drawn when the radio is transmitting.</p> <p>The largest power consumption that you will otherwise see will depend highly on which features you have enabled, and what external circuitry you are using. For example the CPU core will draw 52µA/MHz while active. In order to get a good estimate of the total energy consumption you will need to know:</p> <ul> <li>How often the radio will be active, data rate and intervals between packets</li> <li>How much transmit power the radio needs</li> <li>How much current will be drawn in the radio idle state, this is a sum of peripherals and CPU activity</li> </ul> <p>In order to get these numbers, please consult the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52.v1.0.0/chips/nrf52832_ps.html?cp=1_1_0">Objective Product Specification</a> at the infocenter.</p> <p>Best regards,</p> <p>Øyvind</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/41580?ContentTypeID=1Sun, 03 Jan 2016 01:41:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:8f1cc281-e05f-432d-8db6-60679f343cfextting<p>the most current used for RF module is 10+mA and 0db. But the RF is not continiously work, it&#39;s work durty time is depend on the transmit interval-time, the payload for each package, the latency, etc. which are definded by your code.</p> <p>And you need to meter what the peripherls&#39;s current by your self, and shut off them when necessary.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/41582?ContentTypeID=1Fri, 01 Jan 2016 23:20:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1df6e695-7b14-4dcc-8731-a173d69575a7worldsnexthero<p>I&#39;m assuming bluetooth tx and rx connection for the highest power mode.

For every peripheral the power consumption is described in the product specification.</p><div style="clear:both;"></div>
