esben rosselThe PCBs have finally arrived and after a few trial runs/failures with 0603, there's this:
Opamps are still not fitted, and there was an error in the circuit around the switches.
The PSU-sections work, and when the Dfu bootloader runs the MCU is identified correctly by my laptop, and the LED blinks. In short everything seems to work.
I "just" have to figure out how to setup the chip as a virtual com port.
