Hey, have you seen the ESP-01 ESP8266 WiFi Module? It’s a simple way to connect any microcontroller to WiFi since it has everything built in. You can run your own programs on it or let it handle the Wi-Fi connection for another device.
It’s got its own processing power and GPIO pins, so you can easily connect sensors or other gadgets with hardly any extra parts. Plus, it’s really small and takes up almost no space.
To use it, you’ll need a USB to 3.3V TTL converter and a 3.3V power supply—just avoid using 5V devices because this one works on 3.3V.
It also comes with features like VoIP support and self-calibrating RF, meaning it works in all conditions without needing any extra RF components. Super easy to get started!
Warning: The ESP8266 works at 3.3V. Connecting directly to 5V will burn it! You have to use voltage drivers or logic shifters.
