KiCad Project

To open this project in KiCad 7.0 clone this repository and open the .kicad_pro file in Ruler_KiCad. Next open the PCB editor and go to Preferences > Manage Footprint Libraries > Add Existing (the folder icon below the list of libraries). Then navigate to Ruler_KiCad/ruler_footprints and click "select folder". This is in order to get the custom footprints used in this project.

Ordering

The gerber files needed for ordering can be found in Ruler_gerbers.zip. Simply upload this .zip file to any PCB manufacturer's website.

The recommended specifications for ordering this PCB are as follows:

  • 2 Layers
  • 1.6mm thick FR4
  • Blue soldermask
  • White silkscreen
  • ENIG surface finish
  • <= 1 oz Copper weight
  • Tented vias (doesn't matter as there are no vias)
  • +- 0.2mm Board outline tolerance
  • Remove order number

Using JLCPCB's pricing, the cost of ordering x number of boards has been plotted in Pricing.xlsx.

Questions

How big is the Ruler V2 KiCad PCB?

It measures 155 × 30 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Ruler V2 KiCad use?

38 parts, built around the NE555D. 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 Ruler V2 KiCad KiCad files?

From the ben5049/ICRS-PCB-Ruler repository on GitHub, at the commit this page was made from: the board is Ruler_V2_KiCad/Ruler_V2_KiCad.kicad_pcb and its schematic Ruler_KiCad/Ruler_KiCad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Ruler V2 KiCad design in my own project?

Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
