Identify the hardware first
Read the model and revision printed on the PCB, including suffixes. A controller name such as ESP32 or SSD1306 identifies a family of silicon, not a unique physical board. Compare the connectors, USB port and silkscreen with the reference.
Find the reference
- Start with the printed model code in the top search bar. Add a manufacturer to narrow similar names.
- Choose Entire catalog, Boards & devices, or Displays, sensors & modules. Use Pinout sources only when you need a physical map.
- Open a result and read its coverage label. A product photo helps identify a device; it does not establish a pin assignment.
- Open the pinout at a useful size. Follow the source link for the exact revision and electrical limits.
Keep useful references close
Bookmark boards with Save board. The browser keeps favorites and measurements on that browser profile; the Windows app keeps them locally. Export a workbench backup before moving computers or clearing browser data. A backup stores workbench records, not the complete image library.
