I finally received five packages ordered at the end of June on Aliexpress… They consist of so called “Blue pill” and “Black Pill” and also BMP280 (temperature and barometric pressure sensor) and HTU21D (temperature and humidity sensor) and Air280 (one of many GPRS modem boards). Here is photo of the stuff (I already converted one of “Black Pills” to ST-LINK V2).
Below I will list projects made with this material:
1.Here is explanation how to make your own ST-LINK V2.
2. Tutorial on Blinky and USB serial “Hello World!”.
Thanks for visiting!
