Flipper Zero is a small, open-source device that lets users test, debug, and interact with many wireless systems. It works with protocols like RFID, NFC, Sub-1 GHz RF, infrared, and iButton.
You can use it to clone access cards, replay remote signals, control devices with infrared, or automate tasks through USB. It does not need a computer to operate.
The tool is often used by ethical hackers, developers, students, and tech hobbyists.
It is fully self-contained and portable, making it useful in labs, fieldwork, or security audits.
Flipper Zero runs on an STM32WB55 dual-core processor. It has a 1.4-inch black-and-white screen that works well in sunlight.
A 5-way directional pad and a back button allow you to use the device easily. It also includes a microSD card slot for saving data and adding new apps.
The built-in battery is 2000 mAh and rechargeable.
Bluetooth support is available, but only with an external module.
| Feature | Function |
| RF (Sub-1 GHz) | Capture and replay remote signals from devices like garage doors and smart plugs. |
| RFID & NFC | Read and clone cards and tags (125 kHz and 13.56 MHz). |
| Infrared (IR) | Store and send signals to control TVs, ACs, and other devices. |
| iButton | Read and simulate 1-Wire keys used in access systems. |
| BadUSB | Run keyboard scripts on computers using DuckyScript. |
| GPIO | Connect with and debug other hardware using UART, SPI, or I2C. |
Each function is accessible through the device menu. No computer is required for daily use.
The device is often used in penetration testing, hardware development, and classroom settings.
Some common use cases include:
These tasks are common in cybersecurity bootcamps, automation labs, and DIY electronics projects.
Unofficial Telegram sellers also exist, but many of these sell cloned devices. Use caution.
Flipper Zero is legal to own and use for ethical purposes.
However, many of its functions, like card cloning or signal replay, can be illegal if misused.
Users are expected to:
The tool itself is not illegal, but the way it is used determines its legality.
Flipper Zero is often compared to Proxmark3, Rubber Ducky, and ChameleonMini.
Here’s how they differ:
| Tool | What It Does | Need a Computer? |
| Flipper Zero | RFID, NFC, RF, IR, USB | No |
| Proxmark3 | RFID/NFC only | Yes |
| Rubber Ducky | USB scripting only | No |
| ChameleonMini | NFC emulation | Yes |
There are also Flipper Zero alternatives sold as clones, but many do not support the latest firmware. Use with caution.
Flipper Zero is still under active development.
The latest firmware (v1.3.4, April 2025) includes:
This device is not designed for casual or beginner users.
It is most useful for:
It may not be helpful for people who want a plug-and-play gadget without a learning curve.
Flipper Zero is a multi-protocol testing and emulation device that works without a computer.
It supports RFID, NFC, Sub-1 GHz RF, IR, BadUSB, and GPIO debugging. The device is useful for ethical hacking, automation, and education.
In India, Flipper Zero is gaining popularity, but users should be careful about legality and source reliability.
It is best suited for those who understand or want to learn how low-level devices communicate, and need one portable tool to test them all.
