Design files

  • relay-module-light.kicad_pro — KiCad project
  • relay-module-light.kicad_sch — top-level schematic
  • relay-module-light.kicad_pcb — PCB layout
  • Additional .kicad_sch files — hierarchical schematic sheets
  • models/ — project-specific 3D and mechanical models

Working with the project

Open the .kicad_pro file in KiCad. The design includes files originating from an older KiCad workflow; review schematic links, footprints, design rules, zones, and manufacturing outputs after any conversion or upgrade.

KiCad source files and project-specific libraries are the source of truth. Generated BOM, Gerber, assembly, and fabrication-house outputs are excluded from the repository; regenerate and verify them before manufacturing.

Repository notes

Temporary KiCad state, locks, autosaves, and backup directories are excluded by .gitignore. Board revision, tested KiCad version, manufacturing revision, and hardware/firmware compatibility still need to be recorded when provenance is confirmed.

Questions

How big is the Relay module light PCB?

It measures 103 × 86.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Relay module light use?

70 parts, built around the SN65HVD230D, LM2594M-5.0, AT24CS32-STUM-T and LMR23610. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Relay module light KiCad files?

From the sillevl/spha-rel6-hardware repository on GitHub, at the commit this page was made from: the board is relay-module-light.kicad_pcb and its schematic Power-input-output.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Relay module light design in my own project?

Its repository states no licence, so its author keeps all rights: ask sillevl before reusing the design.
