But what board were you talking about then, the HTCC-AB01?

I did some measurements on my HTCC-AB01 almost 2 years ago and did not notice a higher than documented/expected deep sleep current of the board. I don’t remember the battery voltage of the LiPo used but for measurements I usually use fully charged batteries.

> I did a small test with the standard LoRaWAN.ino example. When powered by LiPo battery via the battery connector the CubeCell board uses only 8.5 uA during deep sleep! smiley +1 When externally powered directly on the 3.3V pin, either by LiFePO4 (3.2V nominal) or by two Alkaline batteries (2 x 1.5V = 3.0V nominal) the CubeCell board uses only 3 to 3.5 uA in deep sleep.
