Overview

Lcd round is an open-source printed circuit board by smkent, from the smkent/pcb repository on GitHub, published under the CC-BY-SA-4.0 licence. It is a 2-layer board with 16 parts on 10 nets, routed with 121 tracks and 32 vias.

It is built around the BSS138. Its parts include 3 resistors, 3 connectors, 2 capacitors and 1 transistor. It belongs with the lEDs and displays boards of this library.

PCB designs

A monorepository of my PCB designs created with KiCAD 8.

Layout and Workflow

Custom symbols and footprints are located in libraries, which is shared between PCB projects using ${KIPRJMOD}.

Individual PCB projects (e.g. *.kicad_pro and friends) are located within within pcb for active projects, or pcb-archived for archived projects.

When a PCB is ordered from a project, fabrication outputs are created and in the project's fab subdirectory and committed to the repository.

Setup

Ensure pipx is installed:

sh
pip install pipx

Install scons:

sh
pipx install scons

Install KiCAD-related dependencies using the system site packages directory:

sh
pipx install --system-site-packages kikit interactivehtmlbom

Build

To render all outputs, simply run scons.

To render outputs for a particular board, run scons -u within that board's project subdirectory.

Licenses

Individual hardware designs in this repository may use different licenses. The following licenses apply unless an included design directory specifies different license(s).

The lcsc KiCAD symbols, footprints, and 3D models libraries were created using easyeda2kicad (pypi), which are from LCSC. More info about easyeda2kicad

Questions

What parts does the Lcd round use?

16 parts, built around the BSS138. 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 Lcd round KiCad files?

From the smkent/pcb repository on GitHub, at the commit this page was made from: the board is pcb-archived/stackable2/lcd-round/lcd-round.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Lcd round design in my own project?

Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
