Got the PCB from OSH-Park, and i started assembly. Already notice two errors with my layout, The battery connecter is turen 180 degres and i missed to connect a 3.3V line. Both issues were easy to solve with a jumper wire and an offplaced battery connector. Next mission i to see if the CPU is alive. I never used a 10pin JTAG with my ST-link before hopefully it will go smooth.

The jumper wire is visible right under C8, and the BATT connector is not pretty but i works for now.
