OpenHW Studio: Intelligent Autowiring & Autocoding System

This document outlines the architecture, features, and component support status for the intelligent circuit generation engine.

[LAUNCH] System Overview

The autowiring system is a hybrid engine (Rust WASM + TypeScript Worker) designed to automate the connection of complex components to microcontrollers (Arduino/ESP32). It handles both physical routing (wires) and logical initialization (code).

Key Features

• Dynamic Helper Injection: Automatically adds required supporting hardware (e.g., L298N Motor Drivers, I2C Pull-up Resistors, External Power Supplies).
• Smart Breadboard Provisioning: Automatically adds and scales breadboards (Mini/Half/Full) based on circuit complexity.
• Anchor-Pin Snapping: Precisely aligns components to the breadboard hole grid for professional-grade layouts.
• Manhattan Routing Engine: Generates orthogonal, non-overlapping wiring paths with high-fidelity lane spacing (7px).
• Universal Attribute Bridge: Ensures high-fidelity serialization of electrical properties (e.g., 12V PSU readout, resistor color bands).
