Stop googling pin 2 vs pin 3. Again.
PinRef is an open-source broadcast cable reference tool built for people who actually make cables. Look up pinouts, build wiring diagrams with correct wire colors, cross-reference connector compatibility, and submit builds from the field.
Built by people who have been burned by a wrong XLR wiring diagram at 2am during a show.
PINOUTS — Every connector you'll touch in broadcast: XLR3, XLR5, XLR4, TRS, TS, NL4, 3.5mm, TRRS, RCA, RJ45, RJ12, DB9, DB25, BNC, Triax, DT12, PowerCON. Tap one, see the pinout.
BUILDS — Pre-built wiring diagrams for real-world cable runs. Wire colors match the actual cable you're holding. Solder side and face view. Continuity test checklist included.
MATRIX — Compatibility grid. Instantly see what can connect to what, what's partial, and what's a field hack.
COMMUNITY — Built something that works? Submit it. Pre-formats the build as an email with importable JSON so we can verify and add it to the main list.
npm install
npm run devOpen http://localhost:3000.
Found a wrong pinout? Have a build that works in the field? Open a PR or submit through the Community tab in the app.
Wire color corrections, new connector types, and new builds are all welcome.
