What Can Flipper Zero Do: Core Functions

Reading, Copying, and Emulating Signals

The short answer to what can flipper zero do starts with one simple action: it listens. The device reads electronic signals from the world around you, stores them in memory, and plays them back later. You select the matching program on the screen, choose Read, and the signal lands in the Flipper's storage. From there, you can emulate it — meaning the Flipper sends out the same signal as if it were the original remote or card.

The table below shows the main signal types and what the Flipper can do with each one.

One important limit: the Flipper can read NFC bank cards but cannot save and emulate them. The same rule applies to rolling-code signals. The Flipper does not support saving non-static signals, so you cannot send a rolling code. That is not a technical constraint — it is a legal question.

These capabilities cover a wide range of everyday devices. You can capture a garage door remote on 315 MHz or 433 MHz, save it, and emulate it later. The built-in sub-1 GHz antenna reaches up to 50 meters. The Frequency Analyzer helps you find the exact frequency a remote uses. A user once read a Heath/Zenith remote on 315 MHz as CAME 12-bit, then discovered the signal was actually Holtek_HT12X 12-bit on 310 MHz AM. The 315 MHz band worked better for transmission even though capturing was harder there.

A Two-Way Remote Control for Geeks

Think of the Flipper as a two-way remote control. It receives signals and sends them. That two-way nature sits at the heart of its capabilities.

On the sub-GHz side, the CC1101 transceiver runs in async mode. This means only four modulations are available: OOK, ASK, 2FSK, and GFSK. The Flipper labels these as AM and FM on screen. AM covers OOK, where the carrier is either present or absent, and ASK, where the carrier amplitude switches between low and high. FM covers 2FSK, where the frequency sits lower or higher than the carrier, and GFSK, where the frequency slides smoothly instead of jumping.

Infrared works the same way. The IR port has a dark filter window that only lets infrared light through. Three IR LEDs transmit, and a TSOP photoreceiver receives. The receiver is sensitive enough that you do not need to point the remote directly at the Flipper — IR signals bounce off surfaces indoors. When the Flipper recognizes a protocol, it decodes automatically. When the protocol is unknown, it records and replays the raw signal exactly as received.

This variety of capabilities makes the Flipper useful for testing your own devices. You can validate radio components, check wireless sensor networks, or explore IoT security. Always test only devices you own or have permission to explore.

Sub-GHz Radio and Infrared

Low-frequency radio waves control many daily gadgets. Garage door openers, gate remotes, wireless doorbells, and weather sensors all speak this language. These sub-GHz radio frequencies occupy three main bands.

Remote Controls and Sensors

The sub-ghz reader and transmitter inside the Flipper acts as a two-way transceiver. It reads a signal, stores it, and sends it back later. You can test a garage door remote, a wireless doorbell, a PIR motion sensor, or a weather station. The Flipper tells you which type of code each device uses.

To catch a signal, the Flipper sweeps every major ISM band. It waits until a transmission rises above the noise threshold. Then it extracts frequency, modulation, pulse timing, and repetition. Finally, it matches the signal against a protocol database and reports a confidence score. Capabilities include fixed-code versus rolling-code alerts. Fixed codes can be replayed. Rolling codes change on every press, so a captured signal becomes useless after one use.

The sub-1 ghz radio frequencies in this band vary by region, yet 315 and 433 MHz dominate consumer gear. Only test sub-GHz remotes and sensors you own or have permission to explore. In most countries, receive-only operation is legal. Unauthorized transmission remains illegal.

TVs and Home Appliances

Television remotes use light signals you cannot see. The infrared transmitter inside the Flipper reads, stores, and replays those light pulses. That means you can capture codes from TVs, projectors, air conditioners, and media players.

The Flipper decodes common IR protocols automatically, including NEC, RC5, SIRC, Samsung32, and Kaseikyo. The chart below compares the address and command bit lengths for these protocols.

The Learn New Remote screen creates a file you can replay later. Saved Remotes handles playback. The community database holds codes for many electronic devices. Follow the same safety rule: only test your own gear or devices you have permission to examine.

RFID, NFC, and iButton

Access Cards and Contactless Tags

Many office badges and building fobs use RFID (radio frequency identification) reader/transmitter technology. The Flipper Zero works as a dual-band tool here. A 13.56mhz nfc module handles high-frequency cards, while a low-frequency frontend covers 125 kHz badges. You can read, write and emulate tags across both bands, which makes the device useful for checking your own access control systems.

The table below shows how the two card families compare.

Low-frequency badges like EM4100 read in a few seconds. You can save the ID, emulate it directly, or write it to a T5577 blank for a physical clone. For NFC, the Flipper reads and emulates Mifare Ultralight cards and can input the UID of ISO 14443-A tags manually. One limit matters: Mifare Classic emulation sometimes fails because some readers run at slightly different frequencies, such as 13.50 MHz. Strong-crypto cards like DESFire resist consumer cloning tools.

Digital Keys and 1-Wire Devices

The iButton is a small metal key, about 16 mm across, that many intercoms and locks accept. It talks over the 1-Wire protocol, where a master device powers the key and requests its ID. The Flipper plays both roles: it reads as the master and emulates as the key itself. Supported types include Dallas, Cyfral, and Metakom, which are common intercom keys in Eastern Europe.

To read one, open the iButton app, choose Read, and touch the key to the data and ground pins. The Flipper shows the protocol name and ID. You can save it and emulate it later against a reader. A CRC error means the UID is corrupted, and the Flipper recalculates the correct byte for you. Only test keys and readers you own or have written permission to examine.

Bad USB, Bluetooth, and GPIO

Keyboard and Mouse Emulation

The BadUSB (computer security attack or vulnerability) interface turns the Flipper into a pretend keyboard or mouse. Your computer sees a genuine Human Interface Device, not a hacking tool. The Flipper then runs a payload written in DuckyScript, a simple command language. You save the script as a .txt file and drop it into the /badusb/ folder on the SD card. Plug in the USB cable, pick your payload, and press Run. The computer types out every command as if you pressed the keys yourself.

Bluetooth extends this trick without wires. The Flipper uses Bluetooth Low Energy advertising packets to appear as virtual devices, such as AirTags or Apple keyboards, to nearby phones. It also supports the Bluetooth HID profile, so it can act as a wireless keyboard. Demonstrations show keystroke injection over short-range Bluetooth into Windows 11 and Android 14 devices. One limit matters: this attack cannot go behind a lock screen. It is just a keyboard.

Hardware Hacking and Scripts

The GPIO (general-purpose input/output) connections open the door to physical hardware work. These pins let you attach external modules, power them from the built-in 3.3V or 5V rails, and control them from the GPIO app. The Flipper also works as a USB to UART/SPI/I2C/etc adapter, displaying debug messages right on its screen. You can scan an I2C bus, dump SPI flash memory, or read UART logs from an unknown chip before writing any code.

This functionality supports firmware flashing, debugging, and fuzzing across many electronic devices. Nova Technology Company (HK) Limited, a HiSilicon-designated (authorized) solutions partner, applies similar chip-level integration expertise to embedded system design and semiconductor solutions. The radio and GPIO capabilities here reward careful, legal testing. Only explore your own cyber landscape.
