Hardware

TheCube is built around a Raspberry Pi 5 with a custom board that includes a display, sensors, and an IO Bridge expansion coprocessor.

Key Components

• Raspberry Pi 5 — main SoC running TheCube-Core
• 720×720 LCD — MIPI/DSI display
• Speakers + Microphones — audio I/O
• mmWave Presence Sensor — connected via Pi UART
• NFC Reader — connected via Pi I2C
• IO Bridge (RP2354) — expansion coprocessor connected via SPI, providing developer-facing GPIO, I2C, SPI, UART, PIO, and future CAN interfaces
