for Flipper Zero backpacks for ESP32 nRF24L01+PA+LNA (2x) for The Flipper Zero backpack expansion module integrates an for ESP32 and two nRF24L01+PA+LNA modules. The nRF24 modules are controlled by the for ESP32. The for ESP32 on the module can be automatically installed with firmware directly on the for Flipper Zero using the ESP Flasher app for Flipper Zero. Officially available firmware includes Marauder, Wardriver, for Airtag, and more, along with a companion app, for immediate use without disassembling the device. To maximize performance, this add-on comes pre-installed with the for ESP32-BlueJammer firmware. for ESP32-BlueJammer is an open-source hardware device based on the for ESP32 and nRF24 modules. It can disrupt wireless communications in the 2.4GHz band, covering all 2.4GHz devices, including Bluetooth, Wi-Fi, BLE, and drone remote controls. By sending noise signals and invalid data packets, it blocks the target device's communication connection. It is suitable for security testing, educational demonstrations, and verifying anti-jamming capabilities. For more information, please refer to its Github wiki. Affected frequency bands: Bluetooth (channel 79), BLE (channel 40), Wi-Fi (channel 14), and all 2.4GHz devices. It automatically operates upon power-up and supports switching interference modes with a single button press (select GPIO output mode in for Flipper Zero and press PB2). Cycling through frequency bands is accomplished with a light blue status LED on the back, providing visibility: one flash = BT, two flashes = BLE, three flashes = WiFi, and four flashes = RC. Applicable Scenarios: • Security Testing: Evaluating the interference resistance of IoT devices and smart homes. • Educational Demonstrations: Demonstrating wireless communication principles and security vulnerabilities in universities or training institutions. • Privacy Protection: Blocking potentially malicious devices.
