The Wemos D1 Mini ESP8266 WiFi Board is a compact, low-cost, and powerful development board designed for IoT, robotics, and wireless electronics projects. Powered by the ESP8266EX microcontroller, it delivers built-in WiFi connectivity (802.11 b/g/n), enabling seamless integration into internet-connected applications.

Operating at 3.3V logic and powered through a 5V Micro USB interface, the board includes an on-board USB-to-Serial converter, making programming and debugging easy without additional hardware. With 4MB of flash memory and a clock speed of 80 MHz (upgradeable to 160 MHz), it provides ample performance for web servers, sensor data logging, and real-time control tasks.

The Wemos D1 Mini offers 11 digital GPIO pins and 1 analog input, allowing easy connection of sensors, relays, displays, and other peripherals. Its small form factor and compatibility with stackable shields make it ideal for space-constrained projects and modular system designs.

Fully compatible with the Arduino IDE and MicroPython, this board is beginner-friendly yet powerful enough for advanced developers. Common applications include smart home automation, IoT dashboards, wireless sensor networks, robot control, remote monitoring systems, and DIY electronics projects.
