Printed Circuit Boards (PCBs)

This repository houses Altium PCB designs for the Heron MK II CubeSat project. It contains pcbs-common as a Git submodule with commonly used schematics.

Export all schematics and board layouts to PDF files so others can easily view them without using Altium.

How to add pcbs-common files into your current Altium project

• Update your GitHub with the pcbs-common submodule

• Run these git commands from your ./pcbs folder:

git submodule init .
git submodule update --remote pcbs-common

• Get the files in your current project
• Project → Add Existing to Project → navigate to your copy of pcbs-common → select relevant files for your design.
• Substitute your current subsheets with the pcbs-common versions
• Open properties of target subsheet (the green box) → find the label indicating from where it’s taking the current subsheet → select the ... → navigate to the pcbs-common version in your project → select and OK
• Synchronize the labels to the subsheet with pcbs-common version
• Right click on the green box → sheet actions → synchronize sheet labels → select the pairs of corresponding sheet symbols → select the bottom arrow option (symbol of a beige box to a blue box [this pushes the version from pcbs-common onto the upper level]).
• When you run out of things to link, select the remaining items in the middle column → add (bottom option) → add no ERCs (X symbols) to pins you are not currently using.

Updating pcbs-common

From the pcbs folder:

$ git submodule update --remote

This will fetch the latest commit of pcbs-common and update your files.

If you get an error about having modified files inside the pcbs-common folder, run the following:

$ cd pcbs-common
$ git reset --hard

This will discard all local changes you have made in the pcbs-common folder. Then, run $ git submodule update --remote again to download the most updated version of the pcbs-common files.
