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.

  • Edfrei That is because power supply and analog power supply for this board are tied to the same point, it is a bad design but is to make the thing as cheap. If You need to use ADC, you better use this product: id 920184
