Just noticed the PCB of SparkFun LoRa Thing Plus - expLoRaBLE also offers 3 jumpers (one is for the LED amongst them), but other than that the board schematics seems to be identic to that of SparkFun Thing Plus - Artemis.
Really do not know how many ready made PCB's for the Thing Plus you have on your stock, however would you ever run out of those it would be great to use the PCB of the explorable board in future production batches of the Thing Plus board. I guess cutting the LED jumper would significantly reduce the power consumption of the Thing Plus board.
Further suggestions in case you are ready to change the board design:
As far as i can figure out, the Apollo3 MCU has an internal Voltage divider (on VDD*2 pad on the schematic), that is lead to the 3V3 output of the power regulator...which does not make much sense as that should output a steady 3V3 while fed with any voltages the regulator can operate with. This renders battery monitoring impossible with this pad.
Other analog pins of the board get saturated above 2.0 volts, so again no good for battery monitoring unless one adds a voltage divider (just what we can see on the OpenLog Artemis).
So adding the same voltage divider or routing the VDD*2 pad to at least 1 analog pin to allow for direct battery monitoring would be welcome.
Add an on-board SD-slot like on most of your recent boards with any MCUs.
