Find your board. Understand every pin.
Explore microcontrollers, development boards, pinouts and hardware revisions.
MCUID connects microcontrollers, modules, development boards, pinouts and hardware revisions. Every published field carries a fixed official source, so you can verify what a pin does — and when a board revision changes it — instead of trusting a copied pinout image.
What you can do here. Look up a chip, module or board and read its identity, revision-scoped facts and interactive 2D pinouts; follow the task-based guides to answer concrete questions like which GPIO drives your onboard LED. Every fact traces to a fixed official source — no unsourced filler pages.
Sections
- Boards
Qualified development board records: revisions, ordering variants and complete header mappings, each tied to a fixed official source.
- Chips
Qualified SoC records: identity and aliases, linking to the boards and modules built on each chip.
- Labs
Reproducible experiments: fixed board revision, SDK and driver versions, full source and the compile receipt for every lab.
- Learn
Task guides for real hardware questions: identify what you are holding, decide if a pin is safe to use, get your first firmware running — and understand the concepts every tutorial assumes.
- Modules
Qualified MCU module records: storage variants, antennas and module-dependent pin restrictions with their exact official conditions.
