Tap a component tile, tap an empty grid cell to place it. Tap a pad, then tap another pad to route a trace on the current layer. Switch between Top and Bottom copper, then run a design check for unconnected pins and same-layer shorts — the same kind of check a real PCB tool runs before fabrication.
This is a layout and routing linter, not an electrical simulator — it doesn't model current, voltage, or whether your circuit performs its intended function. It's a place to practice component placement and two-layer trace routing.
Place at least one component, route what you can, then click “Run Design Check”.
No. This is a layout and routing linter, not an electrical simulator — it checks for unconnected pins, same-layer trace crossings, and board-boundary/overlap issues, the same kind of design-rule checks a real PCB tool runs before fabrication. It does not model current, voltage, or whether the circuit performs its intended function.
This tool doesn't export a fabrication file. If you want to order a physical bare board, use the separate PCB Builder, which configures real fab specs (dimensions, layers, material, finish) and indicative pricing.
Yes — it's free, runs entirely in your browser, and needs no signup. Nothing you place or route is sent anywhere.
