Portable ESP32-S3 Pentesting & Research Tool

A custom-designed handheld device for ethical hacking, wireless security research, and IoT experimentation. Built around the powerful ESP32-S3 microcontroller, this portable tool combines multiple wireless technologies in a compact, battery-powered form factor. Features include Wi-Fi scanning and analysis, Bluetooth Low Energy reconnaissance, Sub-GHz RF communication for 433/868/915 MHz bands, NFC/RFID reading and emulation, and infrared control capabilities. The device features a custom graphical user interface on a built-in display, modular design for easy expansion, and rechargeable battery with power management. Currently in active development with planned features including packet injection, deauthentication detection, and BadUSB functionality.
