:dart: Features

📡 Wi-Fi Tools

Packet Monitor – Real-time waterfall graph of all 14 Wi-Fi channels
Beacon Spammer – Broadcast fake SSIDs (custom or random)
Deauth Detector – Monitor for Wi-Fi deauthentication attacks
Wi-Fi Scanner – List nearby Wi-Fi networks with extended details
Wi-Fi Deauthentication Attack - Send deauthentication frames to disrupt client connections
Captive Portal - ESP32 runs as AP + DNS + web server. Clone networks, force sign-in pages, all before HTTPS/authentication

🔵 Bluetooth Tools

BLE Jammer – Disrupt BLE and classic Bluetooth channels
BLE Spoofer – Broadcast fake BLE advertisements
Sour Apple – Spoof Apple BLE advertisements (e.g., AirDrop)
BLE Scanner – Scan for hidden and visible BLE devices
BLE Sniffer - Scans BLE advertisements, tracking MAC, RSSI, packet count, and last-seen time. Suspicious devices are highlighted
BLE Rubber Ducky - Acts as a BLE keyboard and executes SD card scripts. Keys are released and advertising stops on exit

📶 2.4GHz Tools

2.4GHz Scanner – Spectrum analyzer for 128 channels (Zigbee, custom RF, etc.)
Protokill – Disrupt Zigbee, Wi-Fi, and other 2.4GHz protocols

📻 Sub-GHz Tools

Replay Attack – Capture and replay Sub-GHz commands (e.g., door remotes)
Sub-GHz Jammer – Disrupt Sub-GHz communication across various bands
Saved Profiles – Store and manage captured signal profiles

📺 Infrared (IR) Tools

IR Replay Attack - Capture real IR remote presses, visualize, replay, and save to SD
IR Saved Profiles - Browser for IR captures, preserving signal and carrier frequency for accurate retransmission

🔧 Hardware Overview

ESP32DIV consists of two boards:

🧠 Main Board

ESP32-S3 – Main microcontroller with Wi-Fi and BLE
ILI9341 TFT Display – 2.8" UI display
LF33 – 3.3V regulator
IP5306 – Lithium battery charging and protection
CP2102 – USB to serial for flashing
PCF8574 – I/O expander for buttons
SD Card Slot – Stores logs and captured signals
Push Buttons – Navigation and interaction
Antenna Connector – External antenna support
WS2812 NeoPixels - Giving better feedback
Buzzer - It shares a GPIO with the battery voltage divider, so using it is optional.
