Hardware

The nRFBOX is built around the ESP32 and packed with components for peak performance. Here’s the lineup of key hardware used in the nRFBOX:

• ESP32-U: The brain of the operation, with built-in Wi-Fi and BLE.
• NR24 Gtmini: Enable 2.4GHz operations, including scanning, jamming, and protocol analysis.
• LF33: Voltage regulator delivering a steady 3.3V supply to keep things running smoothly.
• TP4056: Handles lithium battery charging and protection.
• CP2102: USB-to-serial converter for flashing firmware and serial communication.
• SD Card Slot: Stores captured signals, logs, configuration files, and enables easy firmware updates.
• Antenna Connector: Connects external antennas for boosted signal range.
• Push Buttons: Navigate menus and control the nRFBOX with ease.
• 0.96-inch OLED Display: A crisp 128x64 pixel, low-power screen for real-time data visualization.
• NeoPixel (Optional): A configurable LED for cool visual feedback, adjustable via the settings menu.
