If you have been following electronics, gadgets, or tech in general, you probably have heard about Flipper Zero.
Flipper Zero is a device that can listen to, analyze and emulate different kinds of signals, but one of the features that I like the most about the gadget is its ability to listen and analyze Sub-GHz frequencies, or signals that use those frequencies.
I wanted to have that device, electronics is my hobby, so I did part of its functionality, I chose a couple of modules that I bought online and the amazing ESP32 board, also did an Android app that I use as an interface to the electronics.
The tests that I did can be found at the end of this youtube video.
I'm planning to put everything on a PCB board, and pack it inside of a package, so if you wanna see the progress, subscribe to my channel, by clicking on the link: https://bit.ly/3Qyv8pp 😀
