From the project
This folder contains the KiCad PCB layout for the Breadboard Power Supply PCB.
This folder contains the KiCad PCB layout for the Breadboard Power Supply PCB.
The PCB layout was developed from the schematic and includes the component placement, footprints, copper tracks, power connections, and board layout for the 12V input, 5V regulation, and 3.3V regulation sections.
The PCB layout was designed with consideration for component placement, routing, connectivity, and ease of assembly.
