Feature:
Model: STM32F103C8T6
Kernel: ARM32 bit Cortexu2122-M3CPU
Size: 22.86mm x 53.34mm
Debug Mode: SWD
MCU Introduction:
1. The maximum operating frequency of 72MHz
2. Single-cycle multiply and hardware divide
3. 64k Flash program memory
4. 20k bytes SRAM
5. 2.0-3.6V power supply and I / O pins
6. On power-up, power reset (POR / PDR), programmable voltage monitor
7. 4-16MHz crystal oscillator
8. Embedded 8MHz RC oscillator
9. generates CPU clock PLL
10. Sleep Stop Standby mode
11. VBAT power for the RTC back registers
12. 37 Quick I / O ports, the I / O ports can be mapped to 16 external interrupts etc.
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.

Q:
Can you please tell me this chip is original or a clone?

What kind of software do I need to program it? And surely don't advise Arduino, its shit for real world use. Little wank projects yes, but not for real ARM programming.

Arduino IDE meh but it depends on the goal, at software is powerful but also a complete pain to setup any project, for smaller projects, it's fine
I'm using it with ADC DMA, complex timer controls and more without issue

Q:
When I connect to my windows 10 PC, it can't load the driver, I do see the LEDs blinking, where can I find its driver, by default it shows unknown USB device "Device Descriptor request failed"
