I am working on a project that involves the use of the nrf52840 microcontroller, which will be powered by energy harvested from the environment. This means that it will only be powered for short duration in milliseconds and will be without power for extended periods also in milliseconds. I want to understand the power consumption of the nrf52840-dk in two different scenarios:
-
When the board is performing mathematical operations, such as addition and multiplication, and writing the results to flash storage. The sensor connected to the board will be in low power mode and operating at a voltage of 5V and a current of 20mA. I am looking to estimate the power consumed by the board over a unit time, such as 10ms or 1ms.
-
When the board is reading data from a sensor using SPI and I2C protocols. The sensor will be operating at a voltage of 5V and a current of 70mA. I would like to estimate the power consumed by the board over a period of 40ms.
I would appreciate any assistance in understanding the power consumption in these scenarios, as I have found the current characteristics specified in the datasheet to be confusing. An approximate value close to the actual value would be sufficient for my needs.
