Boards, badges & building blocks.

Hobby electronics by Michael Cutler, started in 2020. Explore the KiCad sources, schematics and build notes behind Makeristic's boards and tools.

Some projects were manufactured; others remain unfinished designs. Each repository documents its available files, known issues and reuse terms.

Templates & parts

Feather template
A KiCad starting layout with Micro-USB, battery connector, headers and mounting holes. Derived from arturo182's template.
USB-C Feather template
A USB-C variant of the Feather template. Add the controller, USB-C termination and application circuitry before fabrication.
KiCad component library
Collected and customised symbols, footprints and 3D models for Makeristic projects. Individual assets have different provenance and reuse terms.
