What is it?
Flipper Zero is a portable open-source multi-tool for interacting with digital systems and hardware. It combines LF RFID, NFC, Sub-GHz radio, infrared, iButton, Bluetooth LE and GPIO in a standalone device.
Best fit
It suits hardware engineers, firmware developers, RF/RFID researchers and security teams working in labs or on systems they are explicitly authorized to test. GPIO also makes it useful for UART, SPI and I2C debugging.
Positioning
It does not replace a wideband SDR or a specialist Proxmark platform. Its strength is combining several interfaces in a compact, extensible device.
Use radio, RFID and access-control functions only on your own systems or with explicit authorization.
