Wemos D1 Mini ESP8266 12E Wifi Development Board

The Wemos D1 Mini ESP8266 WiFi developmemos D1 Mini ESP8266nt board ideal for IoT, smart home, and sensor projects. Its small size and built-in WiFi connectivity make it perfect for projects where space is limited but wireless communication is required.

Compatibility

This Wemos D1 Mini WiFi board is fully compatible with the Arduino IDE and NodeMCU firmware, allowing easy programming and development for beginners and professionals. It also supports MicroPython, making it versatile for a wide range of IoT and embedded applications.

Header Pins

All I/O pins support interrupt, PWM, I2C, and one-wire communication (except D0). The board comes with long-pin female headers, standard-pin female headers, and male pin headers. Long-pin headers are ideal for breadboard use while keeping female headers available on top for easy prototyping.

USB Connectivity

The mini ESP8266 includes an on-board Micro USB connector with a USB-to-Serial (UART) converter, enabling simple powering and programming via USB cable.

Important Note

The Wemos D1 Mini ESP8266 is a 3.3V device. Use a logic-level converter when connecting 5V sensors or peripherals to avoid damage.
