Scottina

Scottina functions as a dedicated, portable touch-interface terminal powered by a Raspberry Pi 5 running Kali Linux. The core processing handles the execution of diagnostic scripts, network packet parsing, and custom graphical logic. The system interfaces directly with a 3.5-inch ILI9486 SPI touchscreen that resolves at 480x320 pixels, utilizing a direct framebuffer Python application to render custom user interfaces without relying on a heavy desktop environment. User touch input is registered via an integrated ADS7846 resistive touch controller communicating over the SPI bus. To ensure system stability under heavy processing loads, an active cooler regulates the Raspberry Pi 5 processor temperature, while power is delivered cleanly through an official 27W USB-C power supply connected to the board's power management integrated circuit. Optional modular expansion components—such as a CANable or candleLight board for bus communication, an RTL-SDR dongle for radio frequency analysis, or an ALFA Wi-Fi adapter for wireless assessment—can interface with the Pi via USB or internal headers, allowing the touchscreen front panel to interact with external automotive, marine, or RF physical layers.
