Description

Unlike the bare ESP8266 module, which can be challenging for beginners due to power and programming requirements, the WeMos D1 Mini simplifies everything. It includes an onboard USB-to-UART converter (CH340) and a stable 3.3V voltage regulator, allowing you to program and power the board directly using a standard Micro-USB cable.

Based on the ESP-12F WiFi module, this board offers improved stability and better wireless range compared to earlier ESP8266 versions. It provides 9 GPIO pins with support for PWM, I2C, SPI, and 1-Wire, making it suitable for a wide range of sensor and control applications.

The WeMos D1 Mini supports multiple programming options including AT commands, NodeMCU (Lua), and most popularly the Arduino IDE, making it an excellent choice for both beginners and experienced developers.
