3-Pack OSOYOO NodeMCU ESP8266 Development Boards - USB-C WiFi Module For Arduino

About This Product

If you're into IoT projects or just getting started with microcontroller programming, this 3-pack of OSOYOO NodeMCU boards is an absolute steal! Based on the ESP8266 with ESP-12F module, these little boards pack serious power with built-in WiFi connectivity that makes them perfect for smart home devices, weather stations, or any project that needs internet connection. The USB-C port is a really nice upgrade from the older micro USB versions - it's more durable and reversible, so no more fumbling around trying to plug it in the right way. The board features 32Mbit of built-in flash memory and uses the CH340C serial chip for reliable communication with your computer. At 52mm x 26mm, the size is perfect for breadboard projects and prototyping. What's awesome is the flexibility - you can program these in Lua, AT commands, MicroPython, Arduino IDE, or IOT source code, so you're not locked into one programming method. The open-source community around these boards is huge, so there are tons of libraries and tutorials available online. OSOYOO actually provides detailed tutorials themselves to help you get started quickly with various application examples and full installation guides. The boards work great for smart home automation, industrial monitoring, building automation systems, or just learning about IoT programming. Having three boards means you can work on multiple projects simultaneously or have backups if you somehow manage to fry one (though these are pretty robust). The build quality is solid, and at this price point for a 3-pack, it's one of the best values in the maker community right now. Whether you're a beginner looking to learn or an experienced developer building prototypes, these NodeMCU boards deliver reliable performance and endless possibilities for connected projects.
