Wemos D1 R2 ESP8266 WiFi UNO Development Board

UNO Based ESP8266 Nodemcu Development Board

This development board combines the UNO format with the ESP8266 NodeMCU, allowing compatibility with both the Arduino IDE and NodeMCU.

It features a 32-bit ESP8266 processor with more flash memory than the Arduino Uno, 11 digital I/O pins, and one analog input pin. You can easily connect it using a Micro-B USB cable.

The ESP8266 is a widely-used microcontroller with built-in WiFi, similar to Arduino. However, many ESP8266 ESP-12 boards can be challenging to power or program, as they require a stable 3.3V supply.

This board addresses that issue by making the pin layout compatible with the Arduino UNO. You can use DuPont cables directly and even connect compatible UNO shields, provided they match the pin configuration and voltage requirements.
