Hello,
1) Is it possible to power the STM32F103C8T6 via its pin 3.3v or 5.0v instead via USB? If yes, what is the operating voltage (min and max for each) ?
I read 2V - 3.6V but on which pins?
2) What is the consumption (mA) of this board?
Thanks!

1) You can use 3.3 or 5V pin to power board. 5V pin is wired with USB 5V. Voltage limit depends on voltage regulator used on board. Blue pills will work with up to 5.5V but not less than 3.8V.
3.3V pin powers MCU directly so all is in datasheet: https://www.st.com/resource/en/datashee ... f103c8.pdf

2) 2x ~2-3mA LEDs, up to 50mA MCU.2.0 to 3.6 V application supply
