For PCB designs I really recommend Kicad. It's open source, commonly used and works on Linux and Windows.

It's not that hard to design a PCB with Kicad and order it from Itead. And Itead's prices are very suitable even for individual hobbyists.

Hmmmm I personally is alergic with MCU manufactors that only has IDE/Compiler/debuggers that only works in windows. Isn't STM32 winblows only?

If thats the case it should not be used. I say the same about 8bit Microchip... AVR is better for 8bit (even if it sucks bigtime to user 8/16 bits this days when ARM costs less...

Open project shall use open and platform independent toolchains atleast... (means GCC)

However, I have zero experience with programming these kind op microprocessors. Also, putting this thing on a pcb is a bit out of my reach. Please help if you have serious skills!

IMHO use ARM that works with GCC toolchain and often costs less. see my other posts. And also works with more debugprobes...

Yeah think that too... same for the voltage discussion... batteryvoltage != I2C != mainboard
