Thunderboard EFR32BG22 current consumption
No I just have a BG22 TB. I am powering my board through the pins EXP2 and EXP1, so i just put an ampermeter between my power supply and the pin EXP2.
How would I set the debug mode to off ? I'm just using the on-board debugger and from what I saw, when not used the on-board debugger goes into a very low power shutoff mode (EM4S), consuming around 80 nA typically |

Thanks for your answer.
Ok so I've tried measuring the consumption with the same conditions as the datasheet says. I tested to get the same results as the section "4.6.3 MCU current consumption at 1.8 V" -> now my power supply =1,8V and VDCDC is bypassed
The best I could get is 6µA. It's better thaan the 7µA I had but that's not it. Do you have other ideas ?

I've just tried these examples, the best i can get is 7µA. Any ideas to have a lower power consumption ? Do you manage to measure nanoamps with these examples ?

Thanks for your answer !
Ok so I have way better results now but I still have one question : How do you explain the differences between the values we have and the specs that announces 0.17µA in EM4 and 1,75µA in EM2 ? |

Hi all,
I'm trying to measure how much current my board draw in EM2 and EM4 mode. I've disabled all the peripherals but I can't get better than 300µA in any mode. I would expect to have much less for the EM4 mode but I don't see any difference right now.
I'm powering my board through the pins EXP20 and EXP1. I'm using the soc-thunderboard example and here is the changes I've made to it :
This is my last test before we can choose which product we'll use, thanks in advance for your help :)
