BYTEBOLT One
BYTEBOLT One is an open-source BadUSB platform designed and developed in Austria. It turns a tiny, affordable board into a powerful HID attack and automation tool — emulating both keyboard and mouse input the moment it’s plugged in.
At its core sits the ATmega32U4 microcontroller, programmed through the Arduino ecosystem using the familiar Keyboard.h and Mouse.h libraries. Whether you write payloads in C or use the Arduino IDE, you get full control over what BYTEBOLT One types, clicks, and executes — no proprietary scripting language, no vendor lock-in.
The PCB is designed to match the standard USB 2.0 UDP form factor, making it compatible with a wide range of off-the-shelf USB flash drive enclosures. Pick a shell that suits your use case — discreet, rugged, or custom — and the board drops right in.
- Open source, top to bottom. Hardware design, firmware, and documentation — all released under GPLv3. Study it, modify it, share it.
- Affordable. Built to cost a fraction of commercial alternatives without compromising on capability.
- Modular and hackable. Write your payloads in C or Arduino — no proprietary language to learn. If you can code it, BYTEBOLT One can run it.
