Thanks to KiCAD and PCBWAY things look very nice.
The PCB arrived to my door in 6 days after sending the data to PCBWAY.COM
Time to heat up the soldering iron (vapour phase soldering is my way FYI, not the iron anymore)
Debugging in action, LED blinking, GDB running, Clion as my primary IDE for this project, integrates with CubeMX from ST. New V3 STLINK works great.
The blink was active only 6 days after sending the PCB data to China. How about some fast development!
