This compact computing system integrates a Raspberry Pi 4 Model B running Kali Linux OS for ARM, serving as the central processing unit and software environment. Power is supplied and managed via an onboard battery and charging system, making the device entirely portable. For visual output and primary user interaction, a 3.5-inch HDMI-based touch display connects directly to the Raspberry Pi's video and interface pipelines. Additionally, a secondary SPI touch e-ink display is integrated to function as a specialized keyboard panel. Operating system images and utility tools are stored on an SD card and expanded using a USB drive. All of these core electronic components are housed securely inside custom 3D printed case parts, specifically designed with a base, top, and front to align the displays, ports, and internal wiring into a cohesive handheld form factor. Through this hardware integration, users can execute advanced networking and security software packages—such as Wireshark, Metasploit, and Aircrack-ng—directly on a fully mobile, self-contained Linux workstation.

Frequently Asked Questions
Yes, the Raspberry Pi 4 Model B features standard HDMI ports, allowing you to connect an external monitor for troubleshooting or desktop use, though it will temporarily reduce the device's portability.
You use a computer with the Raspberry Pi disk imager software to flash the Kali Linux OS for ARM image directly onto the SD card before inserting it into the board.
It requires enabling the SPI interface within the Raspberry Pi configuration settings and installing the appropriate drivers or software overlays to register touch inputs correctly as a virtual keyboard layout.
