How to measure current consumption of nRF51822 microcontroller?

[kvrb]

Hi,

I am working on nRF51822 Microcontroller. I am not using any kind of stack I mean Bluetooth etc. I have a simple nRF51822 microcontroller and am running a simple application on it. I would loke to measure the power consumption of the microcontroller or board.

My application is running and displaying on hyper terminal. How can I measure power consumption of this microcontroller..?

Thanks

Hi,

Is your nRF51822 chip monted on a custom board or are you using any development/evaluation kits from Nordic? Check out this answer about general power measurement.

Best regards,

Hi Jorgen,

We are using nRF51822 chip mounted on custom board. Check out this pics also.

I have seen the link which you are provided.

I would like to know which pin of nRF51822 microcontroller is used to measure the current consumption..?

You will have to use some tools to measure the current drawn by the board through the VDD pin, as described in the answer I linked above. There are some more detailed descriptions of how to perform current measurement in the tutorials section.
