vecdec 1.1

by svenscore · Hard · manifest draft — being verified

A Raspberry Pi 4 cyberdeck built around a Sofle Choc split keyboard, an eight-inch touchscreen, a trackball and a Meshtastic radio, with exposed USB and SAO ports.

Svenscore designed vecdec because split-keyboard laptops were not available. Version 1.1 enlarges the display, replaces the earlier gesture sensor with a precise trackball, adds two simplified SAO ports and four front or side USB connections, and isolates the keyboard trays on rubber mounts.

Printed parts

vecdec 1.1 enclosure, keyboard trays and case sleeve — Official version 1.1 STL files are provided for a 250×210mm print bed. The project is CC BY-NC-SA 4.0: attribution, noncommercial use and share-alike terms apply; prints may not be sold under this license.

Notes

Official README, bill of materials, release notes, STL tree and CC BY-NC-SA 4.0 license checked on 2026-10-23. Kept as draft because the BOM leaves several generic connectors, antenna details, internal USB fabrication choices, keyboard components and hardware dimensions or quantities incomplete.
