Flipper Zero

Flipper Zero is a portable multi-tool for penetration testers and hardware enthusiasts: it reads, copies, and emulates wireless signals and digital access systems.

This pocket-sized device functions as a Swiss Army knife for digital exploration, combining multiple hardware tools into a single unit. It features a Sub-1 GHz radio transceiver (300-928 MHz) for capturing and replaying signals from devices like garage door openers and wireless alarm systems. The unit also handles 125 kHz RFID and 13.56 MHz NFC (Near-Field Communication) for interacting with access control cards and badges. With its Infrared transmitter/receiver and GPIO pins, Flipper Zero (running on an STM32WB55 CPU) allows users to control IR devices (TVs, AC units) and connect external hardware for deeper security research and prototyping.
