Arc Raiders: Where To Find ARC Circuitry (Best ARC Probe Routes, Crafting, and Uses)

Arc Raiders: Where To Find ARC Circuitry (Best ARC Probe Routes, Crafting, and Uses) explains how to turn one of the game’s rarest topside materials from a painful bottleneck into a steady resource for shields, Power Rods, and key station upgrades. In this guide, you will learn how to spot and breach intact ARC Probes for guaranteed drops, loot Harvester interiors and crashed ARC couriers, and finally convert surplus ARC Alloy into ARC Circuitry at the Refiner so every raid pushes your account forward.

What ARC Circuitry is

ARC Circuitry is a rare topside material that drops from ARC enemies and ARC activities and is used to craft higher‑end components in ARC Raiders. Item databases list it as a rare material with a stack size of 5, a small weight of about 0.3, and a sell price around 1,000, reflecting its mid‑to‑high value.​

Several key recipes consume ARC Circuitry, including Medium Shields at Gear Bench 2 and advanced items like Power Rods at higher‑tier stations, so it quickly becomes a bottleneck once you move into mid‑game builds. Because it can also be recycled back into ARC Alloy, it sits at the center of an upgrade loop where you constantly balance what to keep, craft, or salvage.​

Main ways to get ARC Circuitry

Guides and community testing agree on three main ARC Circuitry sources: direct drops from ARC enemies and ARC activities, loot from ARC probes and couriers, and crafting it from ARC Alloy at Refiner 3. Basic drops come from looting destroyed ARC machines and their wreckages in high‑activity zones, which is why dense ARC patrol areas and events are emphasized for farming.​

ARC probes are singled out as especially strong sources because each intact probe contains multiple loot compartments with ARC‑related materials such as ARC Circuitry, ARC Motion Cores, and ARC Powercells. Some players also report ARC Circuitry appearing inside crashed or breached ARC couriers, so any ARC‑tech crash site you see on the map is worth looting thoroughly.​​

Best farming strategies

The fastest way to farm ARC Circuitry early is to chain ARC probes during the Prospecting Probes event or similar probe‑heavy world states, since these events temporarily spike probe spawn rates and essentially guarantee circuitry drops from each breach. Video guides recommend breaching a probe, emptying every compartment immediately, then rotating to the next landmark instead of sticking around to fight every ARC machine that responds.​​

Outside of probes, the next best method is to run routes through zones with high ARC presence, clearing patrols and looting every ARC wreck, container, and special ARC device afterward. General loot guides advise building circular paths through areas like Dam Complex, Spaceport structures, and Buried City facilities, since these combine good container density with frequent ARC spawns for more circuitry chances.​​

Crafting and using ARC Circuitry

Once your Refiner reaches Level 3, you can craft ARC Circuitry directly using 6× ARC Alloy for each piece, effectively turning common Alloy drops from ARC enemies into a controlled circuitry pipeline. Upgrading the Refiner to this tier itself costs materials including 10× ARC Circuitry, so most players do a few dedicated field runs for circuitry before they can rely on crafting.​

Recipe tables show that Medium Shield at Gear Bench 2 typically costs 4× Battery and 1× ARC Circuitry, while Power Rod at Refiner 3 consumes 2× Advanced Electrical Components and 2× ARC Circuitry. Guides strongly recommend prioritizing these high‑impact items with your limited circuitry instead of spreading it across low‑value crafts or recycling it back into Alloy, which can usually be farmed more easily.​​

Extra tips and related materials

There is a related material called Burned ARC Circuitry, an uncommon salvage variant that drops from destroyed ARC machines and industrial wreckage and can be recycled into ARC Alloy but cannot replace full ARC Circuitry in high‑tier recipes. Treat Burned ARC Circuitry as extra salvage for Alloy when you are short on metal, while reserving true ARC Circuitry strictly for shields, Power Rods, and crucial workshop or station upgrades.​

Loot and salvage guides stress that you should avoid mass‑selling or mass‑recycling ARC Circuitry early; instead, recycle lower‑tier tech items and only convert circuitry when correcting a temporary Alloy shortage. If you consistently focus your runs on probes, ARC‑dense zones, and then backfill with Refiner 3 crafting, ARC Circuitry turns from an early choke‑point into a manageable part of your long‑term progression in ARC Raiders.​​
