Template design files

The KiCad project lives in the grok-x/template repository on GitHub; these links point at the commit this page was built from.

Template: common questions

What microcontroller does the Template use?

The Template is built around the MKL03Z32CAF4R, from the NXP family.

How big is the Template PCB?

The Template measures 16.8 × 18.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Template?

59 components, from 30 distinct parts. The full bill of materials is listed on this page.

Where can I download the Template design files?

From the grok-x/template repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Template design in my own project?

The repository has no license, so all rights stay with grok-x. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Template without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
