Prototype current consumption high

[annapalu]

Hi all, i development a FW with a low power and when i measure the power consumption using a nrf connector on evaluation board i have 2 ua, and it's ok. Now i have the some hw, on my prototype when i use a nrf52 and the consumption is very high 400 ua. I use an amperometer serial with a power supply to measure the current consumaption.

Somebody have an idea abou the reason?

Thanks, Anna

What is the actual frequency tolerance of the physical crystal you are using?
