In the world of ARC Raiders, survival and progress depend on smart scavenging, and ARC Circuitry is among the most sought-after materials for experienced Raiders. Classified as a Topside Material of Rare rarity, ARC Circuitry plays a key role in crafting advanced gear and upgrading key facilities like the Refiner 3 and Workbench 2.

You can obtain it from ARC Probes, high-tier ARC enemies, or by refining ARC Alloy once the proper station is unlocked. This guide explains what ARC Circuitry is, where to find it, and how to use it effectively to streamline your late-game crafting and progression.

ARC Circuitry: Location

Here are the primary methods and spawn sources, with useful tips.

Looting ARC Enemies & Activities
  • ARC Circuitry drops from destroyed ARC machines and high-tier ARC enemy encounters.
  • For example, enemies such as the “Bastion”, “Sentinel”, “Bombardier”, “Leaper”, “Rocketeer” etc., list ARC Circuitry among their exclusive drops.
  • Tip: Engage zones with frequent ARC machine spawns (or large machine bosses). Clearing those increases your chance for Circuitry drops.
Breaching ARC Probes & Lootable ARC Technology
  • One of the most consistent sources: look for ARC Probes (and other ARC-tech loot points) that spawn during the game.
  • Probes are tall white structures, often emitting a beep/sonic cue, or leaving a smoke trail if crashed.
  • Tip: Prioritise looting Probes early in a run before extraction—faster route, lower risk, good yield.
Crafting at the Refiner (When Unlocked)
  • Once you unlock Refiner 3, you can craft ARC Circuitry using ARC Alloy: 6 × ARC Alloy → 1 × ARC Circuitry.
  • Important: The upgrade to Refiner 3 itself requires 10 × ARC Circuitry. So you’ll need to farm field drops first before this crafting route fully kicks in.
  • Tip: Once the crafting route is open, convert excess ARC Alloy into Circuitry for a steady supply, but don’t convert so much that you undercut crafting/upgrade needs for Alloy.
ARC Circuitry: Map Locations
Location Details
Dam battlegrounds Includes water treatment and precision admin zones. Found from defeating arc enemies like leaper and rocketeer, which spawn frequently here, and from loot containers in the power plant area.
Electrical station Tech-heavy area with arc enemy patrols and containers. Looting containers and server cabinets yields arc circuitry consistently, with arc couriers or probes often nearby.
Barrent city - parking garage Large multi-floor parking area with vehicles. Vehicles can be breached for motors and circuitry parts, useful for refiner level 3 upgrades as an indirect source.
Arc enemy spawn zones High-density areas with enemies like hornet, rocketeer, leaper, and bombardier. These drop arc circuitry upon defeat, with leaper near extract points being a reliable source.
Surveyor vault area Located around the surveyor npc marked by a large blue beam. High-tier loot vaults here contain arc circuitry and other rare components.

How to use ARC Circuitry in ARC Raiders

ARC Circuitry is a gating material for mid-to-late game crafting and workbench upgrades. For example:

  • Medium Shield (Gear Bench 2) uses 1 × ARC Circuitry.
  • Power Rod (Refiner 3) uses 2 × ARC Circuitry + 2 × Advanced Electrical Components.
  • Because it is Rare and required for key upgrades, running low on it creates a progression bottleneck.

Farming Strategy for ARC Circuitry

Here’s a suggested approach to efficiently farm ARC Circuitry:

  • Start each run hunting Probes; track the beeps or smoke signals that indicate ARC Probe landings.
  • After looting Probes, move into zones with high ARC enemy activity (boss machines like Bastion, Bombardier) since those drop Circuitry.
  • Extract once you have a handful (aim for at least enough to approach your next milestone, e.g., 10 for Refiner 3).
  • Once Refiner 3 is available, convert surplus ARC Alloy into Circuitry for sustained supply instead of entirely relying on drops.
  • Monitor your inventory; track how many Circuitry you need for upcoming upgrades so you target runs accordingly.
