Six months of design iterations, sourcing headaches, and a broken oscilloscope later — I am pleased to share a hardware module I designed to extend the Flipper ecosystem for RF security research. This write-up covers the motivation, engineering challenges, capabilities, and responsible-disclosure principles behind the project — and a frank look at a vulnerability that is very much alive in the Maldives today. Left: 3D render of final PCB · Right: Altium Designer PCB layout view Why I Built It The trigger was reading the original MouseJack disclosure by Bastille Networks. It made me realize that a class of peripherals most people assume to be harmless — the cheap wireless mouse on your desk — can be weaponized from a car park. I wanted a research platform small enough to carry in a jacket pocket, native to the Flipper Zero ecosystem, and capable of passive scanning, protocol analysis, and controlled lab tests. What I...
After bricking one router i decided not to try to increase the storage and go with the capabilities which it already have. TL-MR3020 from TP-LINK have a UART but the problem with interconnection was TL-MR3020 out puts 3.3v and Arduino UNO is 5v. So after trying couple for methods trying to level the serial data voltage, finally 74LS04 is used the step up the TX from router to 5v and it was success and Arduino see the data. Then tried to run a shell script from a webpage run in web server inside the router. After couple of frustrations i manage to run with html+javascript...thats a long story... Anyways it works perfectly and more mods will be done soon.
