I cut the track that joins the Cell positive to the Chip VCC and pull up resistors.
The track is easy to find, when looking at the back of the board, with the “Fuel Gauge” text at the top, the track to cut is the one that runs around (from 12 oclock to 3 oclock) the CELL -ve pad in the center of the board and attaches to the VCC pad on the right side.
Once this track is cut, the VCC needs to be connected to a 3.3V (2.5V to 4.5V) supply, but you will have nicely isolated the LiPo voltage from the other supplies you have.
This is for version V11

can you update the images to show scale or pin distances please?
Why didn’t you keep the 4 main pins GND, TX, RX, 3.3V in the same location as the superceeded version?

Soldering that header is goign to be a trick for the at-home crowd.
well the four pins for the SIM dont neeed to be on the edge, they could have been in the centre, in a 3rd row as they not goign to be used by nealry everyone. the sim in on the device anyway. Then there is the secondard IO port. I think challenge is not not increase the foot print of such a nice small device.
Needs to be SMALLER, I want to use this device in a tiny application, it is perfect, but you BOB is too large. Can you move the pins to underneath?
