Differernce in Nrf52 DK versions

[viveknath]

Hello,

I have 3 different nRF52 DK eval boards versions

1. PCA10040 , 1.1.0.           2016.16

2. PCA10040 , 1.2.4.           2019.5

3. PCA10040 , 2.0.0.           2020.8 

When I try to measure the current in boards 1 and 3 , they read varied values on same firmware flashed. (1) at ~3mA average current and with (3) ~49mA

What are the differences? I have cut the SB9 in order to measure the current.

I see the board components seem to have a difference, where can i find the schematics of these board implementation?

I measured current using nrf power profiler kit

Thank you!

HI,

This behavior is observed even with other firmware! Looks like this particular board is damaged.

Thanks for your support.
