Hardware of ESP32-DIV

The ESP32-DIV is a compact yet powerful device, built from two main sections: the Main Board and the Shield. Together, they enable Wi-Fi, BLE, 2.4GHz, and Sub-GHz operations. Below is a breakdown of the hardware components.

🛠️ Main Board

• LF33: Voltage regulator providing a stable 3.3V supply for reliable operation.
• TP4056: Lithium battery charger with built-in protection for safe battery management.
• CP2102: USB-to-serial converter for flashing firmware and serial communication.
• PCF8574: I/O expander to manage multiple button inputs for user interaction.
• SD Card Slot: Stores captured signals, logs, and configurations.
• ESP32-U (16MB): The core microcontroller with Wi-Fi and BLE capabilities, featuring 16MB flash memory.
• Antenna Connector: Supports external antennas for enhanced signal range.
• ILI9341 TFT Display: 2.4-inch screen for user interface and real-time data visualization.
• Push Buttons: For navigating menus and interacting with the device.

🛡️ Shield

• 3 x NRF24 Modules: Enable 2.4GHz operations, including scanning, jamming, and protocol analysis.
• CC1101 Module: Sub-GHz transceiver for replay attacks, jamming, and signal capture.
