ESP32-BlueJammer

The ESP32-BlueJammer (Bluetooth jammer, BLE jammer, WiFi jammer, RC jammer) disrupts various devices using an ESP32 and nRF24 modules, causing plenty of noise and sending unnecessary packets (DoS).

It interrupts:
The whole 2.4GHz broadband! Everything that works on 2.4GHz is being interfered, like:
audio in speakers being transmitted over bluetooth, microphones on 2.4GHz, smartphone connections, WiFi, RC Drones (etc.), IoT devices, smart gadgets, wireless keyboard & mouse, just anything on 2.4GHz!

Ideal for controlled disruption and security testing. Based on 2.4GHz communication.

It has a big range (over 30Meters+ - may vary on your antenna and hardware setup!) on newest Bluetooth versions with casual 2.4GHz antennas, you can easily increase this as well by taking some simple "bigger" router antennas. An amplifier (2.4GHz) may be a good option too!

Remember that jamming is illegal and should not be used with malicious intent!

PCB's with ESP32 and RF-module capability

ESP32-RF DIY-PCB: This PCB can fit an ESP32-wroom-32U/E DevKitC and 2 nRF-modules, along with an 0.96" I2C OLED, LEDs and switches.
Remember: It is not intended for illegal use!
For this one, all you need is listed below:

Required:

• ESP32 Dev Module (Recommended: ESP32-32U CP2102, any ESP32 should work as long as it has the needed pins, 38P required!)
• nRF24L01+PA+LNA (2x)
• 10-100uF Capacitor (2x) (any voltage above 5V)
• 0.96" OLED Display I2C
• Slide Switch (2x)
• LEDs: 3mm LED box
• Resistor kit
• R1 = 1kOhm
• R2, R3, R5, R7 = 47kOhm
• R4, R6 = 100kOhm

Additional:

• TP4056 Charging Module (Micro-USB/Type-C)
• JST PH 2.0 Connector
• 3.7V Li-Ion Battery
• 3rd Antenna: **IPEX to SMA-F pigtail

PRE-SOLDERED: "The Blue ESP"
This is an ESP32 with RF-module breakouts (nRF24/CC1101 etc.) for experimenting.
Remember: It is not intended for illegal use, neither for my project!

Required:

• nRF24L01+PA+LNA (2x)
  Why do you need to get the nRF24's? -> the pinout can be used to connect either nRF24 or CC1101 modules for further experiments with an ESP32 chip. Shop
