BlueJammer-V2 is a two-board RF research platform combining an ESP32 jamming engine with a BW16 5GHz web controller. Features up to 4x NRF24L01 modules, live OLED display, real-time web interface and full UART communication between both boards. Educational purposes only!
Open-source 2.4 GHz spectrum analyzer + NRF24 Jammer for Flipper Zero. Plug-and-play across every firmware. Built for the PINGEQUA 2-in-1 RF Devboard.
Trident — one Flipper Zero app for a 3-in-1 ESP32 + NRF24 + CC1101 expansion board: Wi-Fi/BT via Marauder, a 2.4 GHz NRF24 spectrum analyzer, and a CC1101 Sub-GHz sweep.
Bluetooth LE advertising-spam detector for the Flipper Zero, on the onboard radio. Hears the popup flood on 2402/2426/2480 MHz - and never claims to read it.
2.4 GHz power amplifier design project featuring analytical matching network calculations in Mathcad, PCB layout in Altium Designer, CAD component integration, and full-wave 3D electromagnetic simulation in CST Studio Suite.
2.44 GHz ISM-band microstrip inset-fed patch antenna and 2x2 corporate-fed array designed on Rogers RO4350B substrate. Includes Mathcad analytical synthesis, CST Studio Suite 3D electromagnetic simulations, and mechanical CAD enclosure models licensed under CERN-OHL-P v2.
Dual-mode ESP32-S3 dongle for the R36S & retro handhelds: wireless SF900/SF2000 gamepad receiver (USB-HID) + USB Wi-Fi (RNDIS) dongle. Radio can be transplanted from a dead SF2000 board.
