2 years ago Ok so based on the schematic I can see that the 5v pin only goes to the jumper and the Li-Po chip. Some of the documentation read like I just feed that with 3.3v instead and it would work, however it's kind of mentioned in the section relating to if you weren't cutting the jumper, that's my bad. So it works fine with VBat into Raw, GND to GND, 10/11 to 10/11 (or whatever you define in the code if not Uno/shield default), pin6 to 6 for PWR, and finally...VCC+ to VCC since cutting the jumper and soldering means that's the only entry point into that logic shifting mechanism.
I have a 3.3v Pro Mini and the shield with pins 10 and 11 for comms, vbat going to raw pin, gnd to gnd, vcc (showing 3.3v as expected) going to 5v (for v-logic), and pin 6 to pin 6 to control power. The pin6 power on/off works but I'm not getting any serial communication for some reason. This code works fine when I plug the shield into an Uno. Same code isn't working on the Pro Mini which is the same chip (328p). I also cut the trace for logic level and soldered the jumper to VCC.
