Hi Bill,
I am wondering if you are aware of any way to monitor battery voltage on the Seeeduino Lorawan without having to connect an extra jumper from positive on battery to the A4 and A5 pins?
I found a library which would appear to run on the Arduino Uno but is evidently not compatible with the Seeeduino.

I have my project almost fully operational the only hurdle now is finding a cost-effective battery monitoring solution. The voltage measurement does not have to be exact, I want to send a lora payload when the battery is nearly flat.
