1 Driver Issue I just got an “ESP8266 D1 mini Dev Broad” by a friend of mine, and tried to play around. If you are not familiar, it is an MCU by Espressif company, enhanced by extra features to make it a good dev board. This dev board is really easy to use (as other Espressif products), specially because of Micro USB (or USB-C) port on it. So you can just connect it to your computer and flash the MCU.
