Wemos D1 (Arduino-Compatible) — ESP8266 Wi‑Fi Development Board

UNO Based ESP8266 NodeMCU Development Board

The UNO Based ESP8266 NodeMCU Development Board is designed in the familiar Arduino UNO form factor, combining the flexibility of the ESP8266 WiFi microcontroller with the convenience of the UNO layout. It is fully compatible with the Arduino IDE as well as NodeMCU, making development simple and accessible.

Powered by the ESP8266EX 32-bit processor, this board offers larger flash memory compared to a standard Arduino Uno and features built-in WiFi for IoT and wireless applications. It provides 11 digital I/O pins and 1 analog input pin, and can be easily connected to a computer using a Micro USB cable.

Unlike standard ESP-12 modules that require external 3.3V regulation and manual programming setup, this board integrates the required power circuitry and USB interface. It also breaks out the pins in the Arduino UNO pattern, allowing direct use of DuPont cables and compatibility with many Arduino UNO shields (subject to pin and voltage compatibility).

The board includes an onboard 5V 1A switching power supply and supports input voltage up to 24V. It also supports OTA (Over-The-Air) wireless programming, enabling code uploads via WiFi without a wired connection.

This development board is ideal for IoT projects, home automation, wireless sensor networks, and embedded systems development.
