About These Templates

Each template is based on proven designs I've used in real projects. They include complete schematics, component libraries, and design notes to help you understand the circuit operation.

Templates are provided as KiCad project files with symbols and footprints included. They're designed to be starting points that you can modify for your specific requirements.
