Node MCU ESP8266 Board are so popular? Mainly because of the following features.
Its true Arduino Killer
There is a successor of the ESP8266—the ESP32. The ESP32 combines Wi-Fi and Bluetooth and is dual-core. If you want to start with any of these boards, we recommend getting an ESP32. If you already have an ESP8266, don’t worry. It works great, it has a huge community and it does the job for most DIY IoT projects.
To be able to program the ESP32 using Arduino IDE, you need to add support for the ESP32 boards. Follow the next steps:
Note: if you already have the ESP32 boards URL, you can separate the URLs with a comma as follows:
https://dl.espressif.com/dl/package_esp32_index.json,
http://arduino.esp8266.com/stable/package_esp8266com_index.json
After this, restart your Arduino IDE.
Then, go to Tools > Board and check that you have ESP8266 boards available.
Now, you’re ready to start programming your ESP8266 using Arduino IDE.
Now you are ready to start coding in Arduino IDE for ESP8266 Programming.
