The PCB with STM32F103C8T6 on board works fine, can be programmed from stm programmers. It is one very serious trouble - ADC noise is very very larga, more than 5-6 units becouse of pcb desing. Be carefull with using the pcb as ADC. You can see the ADC noise on Figure.

The edges of the PCB are not burnished, but it is not a big deal - can be done easy with sandpaper. There is one design issue with this 48 pin package - the CAN module and the USB share the same pins, that means that you can't use both in same project.

these boards are the best for beginners to start with it and test there codes before buying a big development board don't forget to put boot loader file with serial programmer or st link inside the board to work with USB

Please note that the MCU on this board is a clone of the ST chip. The ones i got have a CKS32F103C8T6 chip on them. This might not be a problem for you, these boards are cheap. Just keep this in mind if you have weird problems and the boards don't work as expected.

Covid-19の危機により、予想以上に時間がかかりました。 うまく機能し、ピンは半田付けする必要がありました。

It took longer than expected to arrive due to COVID-19 crisis. It works well, the pin had to be soldered.
