ESPnRF24 Jammer

A low-power 2,4GHz wireless jammer based on ESP32 and nRF24LO1+PA+LNA

Features

• A web interface for control and settings
• Multiple jamming modes:
  • WiFi (2.4 GHz)
  • Bluetooth, BLE
  • Zigbee
  • Drones
  • Custom frequency ranges
• Configurable TX power in the interface
• A captive portal to redirect user to the interface automatically
• SSD1306 OLED display support for basic status
• Various configuration options
• And more

Hardware Requirements

For this project, i have used my cheap esp32s3-devkitc-1

However any other ESP32 board with these specs will work too:

• Dual-core chip
• Two usable SPI buses
• 1MB or more ROM + room for SPIFFS

For the componenets:

• 2x nRF24L01+PA+LNA modules
• 2x 100uF electrolytic capacitors of any voltage
• Optionally, SSD1306 OLED display (preferably 128x64)
• Prototype/Bread board, and some wiring

Assembling

• Solder the capacitors across the VCC and GND pins of each nRF24 module
• Wire the display/radio modules to your ESP32 board according to the pinout and your pin configuration in include/options.h

Building

1. Install VSCode and PlatformIO
2. Edit preferences in include/options.h
3. If using a different board, port it into platformio.ini
4. Upload the code, and the SPIFFS filesystem image via platform tasks

WebUI
