Looks good quality. Professional package. Tested all 3 by: After power on the blue led flash slowly. Press button stop flash and press again start flash. Show up in PC on USB. The MCU is marked ST, so seems to be ST original.

Apparently not weact board anymore, but close enough not to matter. Flashed QMK on it through USB using standard procedure, no issues whatsoever. Running a handwired keyboard with Preonic layout. Has been rock-solid so far.

Exactly what I was looking for and easy to setup and run using Arduino. How to use the BOOT0 andNRST to program it took some time to figure out
