Pinbraid: Harness Builder
Map Pins & Verify Continuity
$3.99 · Designed for iPad. Not verified for macOS.
Map connectors pin to pin, generate pinouts and a graded continuity test program, size wire by voltage drop, and export cut lists, BOM, and a PDF packet.
Pinbraid is a private harness desk for prototype teams, electronics labs, robotics builders, repair benches, vehicle projects, and low-volume cable assembly.
Define connectors and their drawing view, map every wire from pin to pin, and record gauge, color, length, and load current. Pinbraid checks the map before you cut: duplicate pins, out-of-range cavities, missing connectors, a net name used on wires that never meet, and power wires whose voltage drop exceeds your limit.
NEW IN 2.0
- Unlimited harness projects, with backup and restore through Files
- Full connector and net editors (rename a connector and every net follows)
- Generated pinout for each connector: used, spare, and conflicting cavities
- Continuity test program built from your nets: expected resistance, pass limit, and automatic grading of each reading
- Isolation groups: wires joined by splices or daisy chains are grouped, and Pinbraid lists the group pairs and spare cavities to check for shorts
- Wire calculator: AWG diameter, area, resistance, temperature correction, round-trip voltage drop, and the thinnest stock gauge within your limit
- Build board: cut list with allowance, bill of materials by gauge and color, contact counts, wire end labels, and assembly gates you can check off
- PDF build packet, plus CSV wire list, BOM, and test sheet
- Meters or feet, light and dark mode, and iPad layouts
EVERYTHING INCLUDED
One purchase, with no subscription and no in-app purchases. Pinbraid has no account, ads, analytics, or tracking. Your projects stay on your device.
Pinbraid documents intended cable assemblies and low-energy continuity results. Confirm connector orientation, pin numbering, conductor ratings, insulation, shielding, test limits, and equipment procedures at the bench.
Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Pinbraid 2.0 is a major upgrade:
- Unlimited projects with backup and restore
- Edit connectors and nets directly
- Generated pinouts with conflict and spare-cavity view
- Continuity test program that grades readings and lists isolation checks
- Wire calculator and per-net voltage drop with gauge advice
- Cut list, BOM, wire labels, PDF packet, and CSV exports
- Fixed: copper resistance and voltage drop now match the AWG table (1.0 overstated them about sixfold)
- Removed the demo verification board and the bundled image plates
- Dark mode, better contrast, and iPad layouts
