Regarding pricing, etc. - right now we're limiting users to 50 harnesses per account. There are no plans to charge for usage below this amount with the current features. I'm hoping people find the tool useful and we can use the feedback to improve it.
Continuing to make some additions and changes to ease use and improve the appearance of the harness design:
[1] Added many standard DSub, M8/M12, and USB connector outlines/pin arrangements to aid in the creation of connectors not currently in the library
[2] In concert with the addition of more connector outlines, added a Magic Button on the Connector and Cable Creator pages that pulls all fields for an entered MPN from Digikey or Mouser. Now, you can just enter your part number (like CDM806-04A-MP-F011-67 for this CUI connector, https://www.digikey.com/en/products/detail/same-sky-formerly...) and the fields will populate automatically. If a standard outline is recognized, you have the option to load the outline and pin arrangement too. For cables, this will pull the core count and other cable properties.
Thanks for the comment...yes, I've had that thought many times. There's on demand fab for about everything else, but no low-volume cable house with auto-quoting and a nice design interface.
Building cables for multiple personal and professional projects, I was frustrated by having to cobble together harness diagrams in Illustrator or Visio, cut snippets from from PDFs for connector outlines, map pin-outs, wire specs, cable constructions, mating terminals, and manually updating an Excel BOM.
Splice gives you:
An SVG canvas to drag-and-drop any connector or cable from your library to quickly route and bundle wires. Assign signal names to wires or cable cores.
Complete part data
Connector outlines, pin-outs, terminal selections (by connector family & AWG), cable core colors & strand counts, wire AWG/color.
Automated BOM & exports parts-ready diagrams, wiring drawings, and a clean BOM in SVG, PNG, or PDF.
Connector & Cable Creators. Connectors or cables not in the existing library can be added with an optional outline and full specs (manufacturer, MPN, series, pitch, positions, IP-rating, operating temp, etc.), then publish privately or share publicly.
