battery connector
I also think that this battery connector is inappropriate.

VCOM and DFU driver
In my Windows 10 environment, VCOM and DFU drivers can coexist, although not completely simultaneously.
In DFU mode … DFU
In normal mode … VCOM -
3 buttons
RST … This button is used to reset the MCU.
BOOT … This button is used to switch between DFU mode and normal mode. Used with the RST button.
PWR … This is the power button of the cellular module, which is not usually used because it can be controlled from the MCU.
