WiFi Security Smartwatch Development Board

Dimensions: 8 cm × 5 cm × 2.5 cm (3.15 × 1.97 × 0.98 inches). Battery capacity: 1000 mAh, providing 9–10 hours of runtime on a single charge. Charging input: 500 mA with visual LED status feedback (red = charging, green = complete). Display: 1.3-inch monochrome SH1106 OLED panel. Core components: detachable antenna, integrated buzzer, multiple exposed GPIO pins, and responsive push-button interface. Enclosure: precision-cut acrylic housing; strap: hypoallergenic silicone for all-day comfort. Power management includes safeguards against short circuits, overcharging, deep discharge, and thermal runaway. Power activation requires a deliberate 2-second button press to prevent accidental operation. The device is purpose-built for teaching and exploring wireless network protocols under controlled, ethical conditions. It executes standard 802.11 management frame operations — such as deauthentication, beacon injection, and probe response spoofing — using well-documented, community-maintained Deauther firmware. No proprietary drivers or cloud dependencies are required; firmware updates and custom scripting are performed via standard USB serial interface. Ideal for university cybersecurity modules, DEFCON-style village training, or self-directed learning paths, this board bridges theoretical networking knowledge with tangible, wearable RF interaction — helping learners visualise signal behaviour, test mitigation strategies, and understand WiFi handshake vulnerabilities in context.
