Why spend extra money on a NodeMCU or a big ESP8266 board when you can make a tiny, pocket-sized Wi-Fi deauther with just an ESP-01 and a small screen? This project shows you how to turn the budget-friendly ESP-01 module into a working deauther with an OLED display, a couple of buttons, and a rechargeable battery. It’s fun, compact, and a great way to learn about the limits of the ESP-01 while building a gadget that actually works.
