2-Layer PCBs
Two-layer boards are the workhorse of electronics prototyping — one copper layer on each side of an FR-4 core, plated through-holes connecting them. They cover the majority of hobby, IoT, and simple digital designs, and they're the fastest and cheapest boards to fabricate.

If your design routes cleanly with signals on top and a ground pour on the bottom — or top and bottom routing with vias where needed — two layers is usually enough. Most Arduino-class projects, sensor breakouts, power supplies, and single-microcontroller boards fit comfortably.
Step up to 4 layers when you need a dedicated ground and power plane for signal integrity, when your part density forces traces you can't route in two layers, or when you're running higher-speed digital buses.
What you can specify
Standard FR-4 (Tg 150 or Tg 170), thicknesses from 0.031" to 0.125", 1 oz or 2 oz copper, and your choice of lead-free HASL or ENIG finish. Solder mask in green, red, blue, black, or white, with white, black, or no silkscreen.
Down to 6/6 mil trace and space and 15 mil minimum holes on the standard process — tighter tolerances are available and priced automatically in the configurator.
Frequently asked questions
How much does a 2-layer PCB cost?
It depends on board size, quantity, finish, and how fast you need it. Enter your specs in the instant quote tool to see a full price grid across quantities and lead times — no login required.
What's the smallest quantity I can order?
You can quote and order from a single board up to 1000. Per-board pricing drops at higher quantities as setup costs amortize.
Are your 2-layer boards made in the USA?
Yes. Boards are fabricated by our US partner shop for quick-turn delivery.
