How to flash ESP Easy on another ESP8266 NodeMCU board Esptool.py is a utility for all ESP8266 boards on the market. It will be necessary to adapt the command by passing the parameters that correspond to your board.
The best way to flash an ESP8266 is by using an ESP8266 development board (e.g. Wemos D1 mini or NodeMCU). Alternatively, you could use a bare-bones AI-Thinker module, and program it using a USB-to-Serial converter. If you don't have such a converter, it is possible to use the internal USB-to-Serial converter of an Arduino to flash the ESP8266.
It is better to know some of the questions and all the answers.
