Make your own Raspberry Pi - PSU

Here’s the Raspberry Pi R3 PCB TH (Through-Hole) model fully populated.
The R3 board is shared on OSH Park which means you can order your own boards which you can assemble yourself!
Components
All parts are fairly common, specially the passives. Here are a few suppliers for the parts you may have a hard time finding.
