About the Pcb ruler
Pcb ruler is an open source PCB design by hildebkg, published on GitHub under the MIT license. It is a 2-layer board measuring 308.8 × 31.8 mm, with 8 components from 5 distinct parts.
Other key parts include the ${SIM.PARAMS}. By type, the board carries 6 resistors and 2 ICs.
From the project
Yet another PCB ruler! Inspired by DigiKey, Adafruit, etc
This project was designed in KiCad 9.0.6.
All footprints used are contained within the \PCB-ruler.pretty folder. I made many of these in other programs and then utilized KiCad's Image Converter tool to generate footprints from screenshots here. Hand-drawn images were created in GIMP. Table-based footprints were created using LibreOffice Calc here. The logic gate/circuit-related footprints were created using KiCad's Symbol Editor and Schematic Editor tools.
