current measurement with an external accelerometer.

[Lei]

Hello there,

I know how to measure the current based on Nordic tutorial. However, if I connected an external accelerometer by connecting Vdd and Gnd from nordic ev kit to accelerometer ev board, the current consumption from external accelerometer could not be measured/reflected with ampere meter. I wonder if there are other VDD on nordic 51832 ev board can be used to power external sensor and count the current consumption into current measurement (ampere meter).

Thanks,

Everything worked okay. I wanted to evaluate the current consumption for nRF52832 + external sensors. True, I can just measure the current through external sensor and add it into total current consumption. But that's not I originally wanted. Ideally, the current measurement through P22 gives overall current evaluation (e.g. 52832+any external sensor).

So my understanding is that the nRF DK currently cannot measure nRF+external sensor through P22. Is it correct? Just want to clarify.

Thanks,

 That's correct!
