# Edge Hardware Node Architecture

At the hardware layer, OcularAI smart glasses function as always-on sensing nodes capable of real-time environmental and behavioral capture. The internal system-on-chip (SoC) is optimized for concurrent sensor polling and encrypted data processing with minimal thermal and energy overhead.

* ARM Cortex-M/A microcontrollers, supporting real-time task scheduling via RTOS;
* multi-modal sensor arrays (camera, IMU, GPS, ambient sensors) interfaced via high-throughput I²C/SPI;
* BLE 5.2 + LoRaWAN radios for low-power mesh syncing;
* hardware-accelerated cryptographic engines for edge-level encryption and key signing.

This design enables each device to operate as a decentralized oracle of its surroundings, seamlessly feeding verified data into the OcularAI protocol with minimal user friction.
