¶ Overview
¶ 1. Introduction
Vision v1.4 is an ultra‑compact single‑board computer designed for autonomous piloting and real‑time video processing in AI‑assisted FPV and robotics applications, optimized for tight size, weight, and power envelopes while maintaining high compute throughput for onboard perception tasks. It targets edge AI workloads such as object detection, tracking, and stabilization, integrating cleanly into digital FPV stacks and embedded systems that require low‑latency processing.
