# Welcome to Protoboard

Protoboard is a hardware validation platform by Delta Robotics Inc. You pick parts, it models them as **ProtoParts** with real interfaces and resources, and it validates the connections (electrical, mechanical, thermal, pneumatic, and network) before you order anything. Flagged risks, adapter suggestions, and a buy-with-confidence parts list, instead of learning by releasing the magic smoke.

> **Validate before you Fabricate.**

## How compatibility works

Compatibility = same interface intent + matching attributes + a valid resource assignment. The validator pairs interfaces, checks hard limits (voltage, current, timing, fit), and proposes an assignment. If intent matches but attributes don't, it suggests minimal adapters. Full detail: [Interfaces and Harnesses](/reference/interfaces-and-harnesses.md).

{% hint style="success" %}
Add parts even if specs feel hazy; the engine tells you what's missing. Prefer defined interfaces over ad-hoc wiring. Fail in software, not in hardware.
{% endhint %}
