Reducing the current drain is a must especially for the LoRa Version of the MKR Series. But there are some pitfalls which must be avoided.

Hi Arduino_Genuino & mstcgn,
thanks for sharing - exactly what I am searching for!!!
I used it with my MKR WAN 1310 (LoRa) controllers. This MKR variant does not have the ADC_BATTERY assignment and the voltage divider in place. The SAMD21 pin PB09 is needed to control the LoRa chip. I just build the voltage divider and used a other free analog pin (A1 in my case). Works great too...
