Electronic Circuit is the core IC2 crafting ingredient that unlocks nearly every basic machine.
Guide
Mine Redstone Ore at Y-level 0–16 with an iron pickaxe to collect at least 4 Redstone Dust per circuit you plan to make.
Craft Copper Cable from copper ingots in the IC2 wiring recipe, then combine each cable with 1 Rubber on the crafting table to insulate it.
Smelt iron ore in a Furnace or Electric Furnace. One ingot is enough for a single Electronic Circuit.
Place Redstone in the 4 corners, Insulated Copper Cable in the 4 edge slots, and the Iron Ingot in the center of the crafting grid.
Combine the Electronic Circuit with a Machine Block to craft Macerator, Extractor, Compressor, Electric Furnace, or use it as part of the Advanced Circuit recipe.
It is the main crafting ingredient for almost every basic IC2 machine, including Macerator, Extractor, Compressor, Electric Furnace, Mining Drill, BatPack, and MFE energy storage.
Place 4 Redstone in the corners, 4 Insulated Copper Cable on the edges, and 1 Iron Ingot in the center of a 3x3 crafting grid to produce one Electronic Circuit.
Craft Copper Cable from copper ingots using the IC2 cable recipe, then combine each cable with 1 Rubber on a crafting table to insulate it.
No. The Electronic Circuit is a crafting item only — it stays in your inventory and crafting grid and has no in-world placement.
The Advanced Circuit is crafted by surrounding one Electronic Circuit with Redstone, Glowstone Dust, and Lapis Lazuli, and unlocks higher-tier machines like the MFSU and HV Transformer.
