Guide for configuring path variables and libraries
[!NOTE] Before you start, please include the appropriate libraries and path variables to ensure components and their resources can be loaded correctly!
1. Configuring path variable
2. Configuring libraries
[!NOTE] Configure symbol libraries and footprint libraries according to the README files located in each generation's directory. Images shown here are only for demonstration purposes only.
Adding 3D models
- Copy the .step/.wrl files to
EPx/Libraries/3d_modelsfolder - In the footprint editor (press Ctrl+E on a footprint in the PCB editor), open footprint properties, navigate to the 3D Models tab, and select the 3D model file with the folder icon to the left of the Show checkbox.
- The path should be replaced with
${NTURT_KICAD_ROOT}/EPx/Libraries/3d_models/..., if not, then you will need to set up the path variable. - Adjust the position of the model.
[!NOTE] For a part that a 3D model would be helpful, if it is a part that came with KiCad, then consider "Save as" in the footprint editor to the project library, then edit the 3D model.
If it is already from a project library, remember to select "Open in library XXX" if it says "Editing XXX from board." on top. After you're done, right click the footprint in the PCB editor and select Update Footprint, check Update/reset 3D models.

Questions
How big is the INV Diff2Single PCB?
It measures 10.3 × 16 mm and has 2 copper layers, 1.6 mm thick.
What parts does the INV Diff2Single use?
12 parts, built around the INA333AIDGK and REF3133AIDBZR. 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 INV Diff2Single KiCad files?
From the NTURacingTeam/nturt_kicad repository on GitHub, at the commit this page was made from: the board is EP6/Powertrain_Group/INV_Diff2Single/INV_Diff2Single.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the INV Diff2Single design in my own project?
Its repository states no licence, so its author keeps all rights: ask NTURacingTeam before reusing the design.
