So, I have a Wemos D1 mini board and everything works fine, but there is a little strange thing going on. I downloaded the board managers and libraries and according to the tutorials, there should be a "Wemos D1 R2 & mini" option to select the board, like here:
But all I have is "Wemos D1 R1". I can select it and I have successfully uploaded the blink sketch, it is just strange.
Oh and an other question. Does the "CPU" frequency option changes the actual frequency of the chip? I thought it is much more complicated to change frequency, I heard that it is not possible the run the ESP8266 on 160MHz while programming it with Arduino IDE.
