Features
- Keystroke Injection: Execute commands stored in a
script.txtfile. - Supports Rubber Ducky-style Scripts: Commands like "DELAY", "REM", "STRING" and special keypresses.
- Compatible with Spanish Keyboards: Fully supports keystroke injection on systems using the Spanish (ES) layout.
Software
-
STM32CubeMX: Recommended to use the latest available version (tested with v6.16.0).
Download from the official ST website: https://www.st.com/en/development-tools/stm32cubemx.html -
STM32CubeIDE: Recommended to use the latest available version (tested with v2.0.0).
Download from the official ST website: https://www.st.com/en/development-tools/stm32cubeide.html -
KiCad: PCB design done using KiCad 9.0.
Hardware
- Pentesting RD Board: Custom board included in the project schematics and hardware files.
- MicroSD Card: Must be formatted as FAT16 or FAT32 to store the
script.txtfile.
🔮 Future Changes
Future updates may include:
- Power LED Indicator: Add a small LED to show when the device is powered and running.
- MicroSD Script Status LED: An LED that indicates when the card is present, when no script is found, and flashes on each keystroke during script execution.
- Additional Commands: Extend the scripting language with new commands for improved automation and more advanced keystroke control.

Questions
How big is the Pentesting rd schematics PCB?
It measures 19 × 44 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Pentesting rd schematics use?
22 parts, built around the STM32F042C6T6, TF-01A, USBLC6-2SC6 and XC6206P332MR-G. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Pentesting rd schematics KiCad files?
From the 51n0nGG0/pentesting_rd repository on GitHub, at the commit this page was made from: the board is pentesting_rd_schematics/pentesting_rd_schematics.kicad_pcb and its schematic pentesting_rd_schematics/pentesting_rd_schematics.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pentesting rd schematics design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
