MiNi is still an ESP8266 development board,It comes installed with the latest ESP8266 software. Please note that the ESP8266 does only support 2.4GHz.You can also use it to develop your own software. It is simple to use, just like any other ESP8266 development board. Function: Attack: Disconnect 2.4G WiFi Beacon: Create fake networks Probe:Confuse wifi s Packet Monitor:Display wifi traffic GPIOs and hardware : Display: SH1106 1.3inch OLED Display SDA: GPIO 5 Display SCL/: GPIO 4 WS2812b LED: GPIO 15 Button Up: GPIO 12 Button Down: GPIO 13 Button Select: GPIO 14 High Light LED: GPIO16 All ESP8266 pins break out. What makes it special? Only ~80mA power usage TP4056x power solution Included 5dB antenna All GPIO breakouts and 3.3 and 5V output 2 LEDs to indicate battery charging status (Red:Charging,Green:Full) Disclaimer This project is a proof of concept for testing and educational purposes. Neither the ESP8266, nor its SDK was meant or built for such purposes. Bugs can occur! Use it only against your own networks and devices!
