Sample KiCAD projects

Here are my random sample projects for KiCAD.

Tested under OpenSUSE LEAP 15.2 with this package:

text
rpm -q kicad
kicad-5.1.8-lp152.2.3.1.x86_64

If your KiCad crashes on Intel i915 card, you can try this tip from https://wiki.archlinux.org/title/intel_graphics

To run schematic editor:

bash
MESA_LOADER_DRIVER_OVERRIDE=i965 eeschema

Or run whole KiCad:

bash
MESA_LOADER_DRIVER_OVERRIDE=i965 kicad

Projects

  • tz1-mvb/ - simple AF multivibrator from TZ1 kit (was "tranzistor tester kit 1" sold around '85 in socialism era).

Questions

How big is the Tz1-mvb PCB?

It measures 49.5 × 33 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Tz1-mvb use?

11 parts, built around the BC547. 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 Tz1-mvb KiCad files?

From the hpaluch/kicad-examples repository on GitHub, at the commit this page was made from: the board is tz1-mvb/tz1-mvb.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Tz1-mvb design in my own project?

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