Quick Links

Fallout 4 introduced settlement building into the popular post-apocalyptic RPG franchise. This was fleshed out further by a series of workshop DLCs. You can turn your corner of the barren wasteland into a fortified town filled with settlers and shops. This means that all the junk you can find in the wasteland can be used to build your settlements.

Circuitry is one of the most important crafting components in the entire game. It comes in handy for upgrading high-tech weaponry like laser rifles and building electronic defenses like turrets. It can be difficult to find in the Commonwealth, but this guide will show you where to look for circuitry.

You can also purchase circuitry in shipments. Shipments are junk items bought in bulk from certain vendors. They can be expensive, but a convenient way to get a lot of components quickly. Purchase the shipment note to redeem it at your settlement. You can also scrap the note to immediately get the components. Here are the locations and vendors where you can buy circuitry shipments.
