Poke at the physics

Every simulator here is also embedded in the module that teaches it. This page collects them so you can come back and play without re-reading.

Flipper Screen

Drive the Sub-GHz menus with a D-pad. Learn the menu tree before you touch the real device.

A simulated spectrum analyzer with a live noise floor. Press a "remote" and watch its peak appear.

A mystery device transmits. Read the peak and name the frequency. Five in a row earns the Tuned In badge.

Type bits, choose OOK or FSK, and watch the data ride the carrier.

Wavelength and antenna length from frequency; dBm to milliwatts and back.

Turn a pulse train into bits the way the Flipper's Read mode does.

A remote, a receiver with an acceptance window, and a Flipper that captures and replays. See exactly why a copy works once, then stops.

Given a scenario, pick the right Flipper tool: Read, Read RAW, Frequency Analyzer, or "stop — that's rolling code."

The glossary as flip cards. Space to flip, arrows to move.
