// about

One firmware.
Every surface.

Flint is an offensive security research firmware that consolidates the most complete and battle-tested capabilities into a single, cohesive platform. WiFi, Bluetooth, NFC, RFID, SubGHz, IR, SDR, GPS, BadUSB — all in one tool, running on any Linux hardware. Built for authorized testing, red-team engagements, and hands-on research.

// hardware

Runs everywhere.

Flint is not tied to any single device. It runs on a growing ecosystem of hardware — from pocket-sized computers to dedicated radio tools and GPIO boards. One firmware, any target.

Active
M5Stack CardputerZero
Primary target. Pocket-sized Linux computer with built-in keyboard, 320×170 display, WiFi, and Bluetooth. The original Flint platform.
Active
Raspberry Pi
Full Linux, GPIO pins, USB host, and all major wireless radios via HATs. Ideal for stationary setups or high-performance field deployments.
Planned
GPIO Boards
Direct GPIO access for custom hardware setups — antennas, sensors, serial devices. HAL abstraction maps pins to tool capabilities.
Planned
USB Accessories
Alfa adapters, RTL-SDR dongles, Ubertooth One, HackRF, Proxmark — plug-in radios auto-detected and exposed to the tool layer. MT7612U and AR9271 USB adapters are recognized for monitor mode WiFi tools.
and more
The HAL is designed to be portable.
If it runs Linux, Flint can run on it.

// responsible use

For research. Not for harm.

Flint exists for security research, education, and authorized testing — red-team engagements, penetration tests, CTFs, and assessing equipment you own. It is a tool for understanding and hardening systems, not for attacking them. We do not condone or support illegal activity.

✓ Get authorization

Only use Flint on systems you own or have explicit, written permission to test. No exceptions.

✓ Respect the law

Follow local laws on radio frequencies, telecommunications, and privacy. Rules vary by region — know yours.

✗ No unauthorized use

We do not support unauthorized access, interception of communications, or disruption of services.

You are solely responsible for how you use Flint and for complying with all applicable laws and regulations.
