Description
This repository has all CAD files for the Analog Shield board used in the University of Toronto, Department of Physic, "Introduction to Electronics course."
This board is used to train graduate students first and foremost in through hole solder techniques. As part of the training in the course they will as learn analog front end, digital IO design methods as well. Other than a teaching aid there is not intended practical use for this board.
The CAD program used to design this board is KiCAD which open source and free to use. The Interactive Html BoM plugin was used to generate the interactive bill of materials html file.
Files
- Gerber Files are located in the fabrication folder
- There is an Interactive bill of materials html file that you can use to assist you in assembling the board.

Questions
How big is the Analog shield PCB?
It measures 68.6 × 53.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Analog shield use?
49 parts, built around the LMT84LPM, TLV2472AIP, PEC11L-4220F-S0015 and PPTC062LFBN-RC. 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 Analog shield KiCad files?
From the perc-sw/analog_shield repository on GitHub, at the commit this page was made from: the board is analog_shield.kicad_pcb and its schematic analog_shield.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Analog shield design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
