Maybe time to re-evaluate use of STM32F103 and use something newer like the STM32L476 Lower power, faster, better features, proper USB DFU support - but I haven't compared pinout... Maybe check it out in STM32Cube? There's active development for Arduino support https://github.com/GrumpyOldPizza/arduino-STM32L4

I went through a bunch of chips to make sure the layout is compatible with as many chips as possible. See https://github.com/PaxInstruments/labwiz-board/issues/50. STM32L476 is not on the list, but I'm not sure why. Was that chip released after September 5th?

I just went through CubeMX and all the pin mapping appears to work out.

Great! The L4 series look really nice. I believe it was released about 12 months ago, but it may not have been added to STMCube32 till later. I only started looking at it recently, although I'm more interested in its little brother the L432

I think we're good on the bootloader hardware. Closing...
