About the Power supply PCB

Power supply is an open source PCB design by nunosousa, published on GitHub. It is a 2-layer board measuring 82.5 × 127 mm, with 49 components from 30 distinct parts.

Other key parts include the LM317KCS. By type, the board carries 17 capacitors, 9 diodes, 9 resistors, 3 ICs, 3 connectors and 2 inductors.

It belongs with the power & battery designs in this gallery.

From the project

An old school SCART switcher. Its main purpose will be to automaticaly detect and switch the video output to the active input video source.

This folder contains de PCB projects for the main PCB switcher board and for a separate power supply.

Due to the size of the main switcher board, I decided to make the power circuitry in a separate board so that if there is any issue with it, I don't have to roll a new (and expensive) whole PCB with everything.

Power supply: common questions

How big is the Power supply PCB?

The Power supply measures 82.5 × 127 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Power supply?

49 components, from 30 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Power supply design files?

From the nunosousa/SCART-switcher repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Power supply design in my own project?

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