BYTEBOLT One FAQ
Is BYTEBOLT One open source?
Section titled “Is BYTEBOLT One open source?”Yes. Hardware design, firmware, and documentation are released under the GPLv3 license. The source repository is on Codeberg.
What microcontroller does BYTEBOLT One use?
Section titled “What microcontroller does BYTEBOLT One use?”The board is built around the ATmega32U4 with Full Speed USB 2.0, programmed through the Arduino ecosystem. 32 KB of flash is available, with 4 KB reserved by the bootloader.
Does it use a proprietary scripting language like DuckyScript?
Section titled “Does it use a proprietary scripting language like DuckyScript?”No. Payloads are written in native C or Arduino using the standard Keyboard.h and Mouse.h libraries. If you can write C, you can write a payload — no vendor-locked interpreter and no scripting dialect to learn.
Can I change the USB Vendor ID (VID), Product ID (PID), and product name?
Section titled “Can I change the USB Vendor ID (VID), Product ID (PID), and product name?”Yes. Override leonardo.build.vid, leonardo.build.pid, and leonardo.build.usb_product in a boards.local.txt file in your Arduino profile path. See the VID/PID page for the full configuration, including the matching boards.txt entries the IDE needs to detect the board after a change.
Which keyboard layouts are supported?
Section titled “Which keyboard layouts are supported?”The Arduino Keyboard library ships built-in layouts for Denmark (da_DK), Germany (de_DE), Spain (es_ES), France (fr_FR), Hungary (hu_HU), Italy (it_IT), Portugal (pt_PT), Sweden (sv_SE), and the US (en_US). Custom layouts (for example the Swiss de_CH layout we publish) are supported as well — see Keyboard Layout.
Can each device be uniquely identified?
Section titled “Can each device be uniquely identified?”Yes. Every ATmega32U4 carries a 10-byte fabrication ID in its signature row (0x0E–0x17). A patched USBCore.cpp exposes those bytes as an 18-character hex USB serial, giving each board a per-chip identifier. Details on Unique ID.
What case or enclosure can I use?
Section titled “What case or enclosure can I use?”The PCB follows the standard USB 2.0 UDP form factor (24 × 11 × 1.4 mm), so it drops into the majority of off-the-shelf USB flash drive shells. A default case is included; custom and bulk enclosures are available on request — see Cases.
Is there a USB-C variant?
Section titled “Is there a USB-C variant?”Not yet. The current revision is USB-A in the standard USB 2.0 UDP form factor. A USB-C variant is on the roadmap but has no committed release date.
Is BYTEBOLT One CE compliant?
Section titled “Is BYTEBOLT One CE compliant?”Yes, BYTEBOLT One is CE compliant. See the comparison table for how it compares against other BadUSB devices on CE, killswitch, tracking, and licensing.
Who develops and sells BYTEBOLT One?
Section titled “Who develops and sells BYTEBOLT One?”BYTEBOLT One is developed and sold by LA&GL Embedded Solutions in cooperation with BYTEBOLT. Bulk pricing and custom enclosures are available — get in touch.
Is it legal to use a BadUSB device?
Section titled “Is it legal to use a BadUSB device?”BYTEBOLT One is intended exclusively for authorized use: penetration testing engagements with written permission, security research, education, and personal lab environments. Unauthorized use against systems you do not own or do not have explicit permission to test is illegal in most jurisdictions. Buyers and users are fully responsible for ensuring their activities comply with applicable law.
