FAQ
What KiCad version do the files use?
All files are saved in KiCad 8.x format. They open in KiCad 7 with a one-time migration dialog.
Can I use the template in a commercial product?
Yes. Once purchased, you receive a perpetual licence to use and modify the design in any number of products, including commercial ones.
Are the BOMs kept up to date?
We review BOMs quarterly and push updates when components are discontinued or better alternatives become available. All updates are free.
What if my fab parameters differ (e.g. 4-layer board)?
The design notes explain which constraints are fab-specific. Upgrading to a 4-layer stack is straightforward and covered in the integration guide.
