From the project
A 555 timer based servo controller designed in KiCad, including the schematic, PCB layout, 3D model, and fabrication files
A 555 timer based servo controller designed in KiCad as part of my PCB design learning journey. The project focuses primarily on the PCB design workflow, including schematic and footprint selection, component placement, routing, 3D visualization, design-rule verification, and preparation of fabrication files.
- Designed in KiCad 10.0 as a PCB design learning project. - Uses a 555 timer to generate the servo control signal, with a potentiometer for adjustment. - Includes the complete KiCad project, PCB documentation, 3D views, ERC/DRC reports, Gerbers, drill files, BOM, and position file. -…
