Cyberdeck is a versatile custom machine designed to transform an ESP32 equipped with an ILI9341 TFT display, an analog joystick, and two buttons into a standalone handheld multi-tool. The system features an intuitive menu interface with joystick controls. It supports RFID and NFC reading through PN532 and RDM6300 modules, allowing captured codes to be saved directly into non-volatile memory. Wireless features include hosting a local Wi-Fi Access Point with an embedded web server for remote signal triggering, as well as a BLE packet generator for wireless testing. A built-in hardware diagnostic utility allows for easy real-time testing of connected components, buttons, and joystick movement. The firmware also showcases a custom 3D engine capable of rendering interactive, rotating geometric shapes in real time. Finally, it includes built-in retro mini-games such as Snake and Cyber Race with persistent high score tracking.
