HiLetgo WeMos D1 R2 WiFi Board - ESP8266 ESP-12F Development Board For Arduino

About This Product

Maker and IoT enthusiasts, this HiLetgo WeMos D1 R2 development board is an awesome, affordable way to add WiFi capabilities to your projects! Based on the ESP-8266EX with ESP-12F module, this little blue board packs some serious features - 11 digital I/O pins, 1 analog input pin, and the super cool OTA (Over-The-Air) capability that lets you upload programs wirelessly without needing to physically connect to your computer. It's fully compatible with Arduino IDE, so if you're already familiar with Arduino programming, you'll feel right at home. The onboard switching power supply is really handy too - it can handle input voltages up to 24V and outputs a stable 5V at 1A, which means you can power other components directly from the board. The R2 version is an upgrade from the previous model with improved pin locations and better NodeMCU compatibility. Whether you're building smart home devices, weather stations, IoT sensors, or any project that needs internet connectivity, this board delivers reliable WiFi performance at a fraction of the cost of many other options. The CH340 chip handles the USB-to-serial conversion, and drivers are readily available for all major operating systems. The community support for these boards is massive too - there are tons of tutorials, libraries, and example projects online to help you get started. The compact size makes it perfect for embedding into projects, and the built-in 3.3V regulator means you don't need external regulation for most sensors and components. For the price, you're getting an incredibly versatile development platform that opens up endless possibilities for connected projects. It's become a favorite among DIY smart home builders, students learning about IoT, and professional prototype developers alike. If you've been wanting to experiment with WiFi-enabled projects but found other options too expensive or complicated, this WeMos D1 R2 is the perfect starting point that won't break the bank!
