LabWired The easy way to build hardware
Parts

What LabWired simulates, part by part.

All 214 placeable parts. 111 have a device model behind them; the rest are pins, wiring, instruments or annotations — and each page says which, plus how that model's correctness was established. Of the modelled parts, 3 have been checked against a capture from real hardware and 108 were built from the manufacturer's register documentation without anything physical placed next to them. We publish that distinction because a simulator that will not tell you where it is weak cannot tell you when your firmware is wrong.

Simulated device models (111)

The firmware talks to these over the real bus and gets device-accurate responses.
