There have been design changes between the currently shipped revision C/D dev kits and the revision B schematics/project files available here.

One such example is the addition of the FET2 transistor to control the VDD pins on the UEXT1 connector and CON1 header.

Please make the revision C/D development kit schematics and KiCad project files available in this repository.

I'm trying to build SOFTWARE/BB-STM32WLE-WAN project with CubeIDE but it gives me error about missing iis2mdc/iis2mdc_reg.h

It seems iis2mdc in SOFTWARE/BB-STM32WLE-WAN/Core/Src might be a symbolic link or something but in my cloned project it's just an empty directory.

I thought it might be a git submodule but I cannot find .gitmodules file anywhere.

Should I somehow import this library?

I tried cloning couple of projects like this or this and use them in place of iis2mdc but it results in other errors and feels like a wrong direction.

Thank you in advance.

Maybe I did not understand the schematic correctly, but I don't see a way to cut the power supply for the STM32L052 used for programming when the board is run from a battery. This leads to excessive power consumption because:

1. Two MCUs are powered.
2. I guess the firmware for the programmer is not optimized for ultra-low power consumption. It even keeps on some LEDs when USB is disconnected.

Is there any way to minimize the power consumption of the board?
