A VALLEYTECH SOLUTIONS PROJECT
The maker reference wiki
Find a reference, understand its limits and get back to building. Guides and catalog directories you can read without opening the app.
Start at the workbench
Find the exact board, open a useful pinout and keep its source and revision close.
How to read a pinout reference
Distinguish physical connector positions, GPIO names and alternate functions before wiring.
GPIO, I²C, SPI and UART
A quick introduction to the signal names you will meet in maker pinout sheets.
Identify displays and sensors
Use controller, interface, board revision and physical connectors to distinguish similar modules.
Find a power-module reference
Distinguish buck, boost, buck-boost, charger and protection records before selecting a pinout.
Search, themes and saved boards
Use keyboard search, scope filters, dark or light mode, original downloads and workbench backups.
Coverage, sources and review status
What each coverage label means and where the remaining documentation gaps are recorded.
Help improve the maker reference
Report errors, contribute sources and request hardware with enough evidence to review.
