Droid PCB

Your Pocket-Sized PCB Workshop Has Arrived

You’re staring at a schematic, wondering if that trace width will handle the current. Or maybe you’re sketching a layout on paper, hoping it fits the enclosure. That uncertainty — the “will this work?” feeling — is exactly what Droid PCB was built to kill. This app turns your Android device into a full-fledged printed circuit board design tool, letting you draft, simulate, and verify circuits anywhere, without a laptop. No more waiting until you’re back at the desk to test that hunch.

The Workspace That Follows You

Open Droid PCB and you’ll find an interface that feels like a stripped-down EDA suite, optimized for touch. The canvas responds to pinch-to-zoom and drag with zero lag, even on Android 4.2.2. You place components from a library that covers resistors, capacitors, ICs, connectors, and common modules — all with standard footprints. Routing traces is a matter of tapping start and end points; the app auto-routes or lets you draw manually with your finger or a stylus. You can rotate, mirror, and snap components to grid, just like on desktop tools.

The real game-changer is the real-time design rule check (DRC). As you route, Droid PCB highlights clearance violations, missing connections, or overlapping pads. You’ll see red markers appear instantly, so you fix errors before they become expensive prototypes. The app also includes a netlist viewer and a basic simulation engine — you can verify continuity and check for shorts without leaving the canvas.

What Makes This App Stand Out

• Offline-first workflow: No internet required for core design. Your projects live on the device, synced only when you choose.
• Gerber export: Generate standard Gerber RS-274X files directly from the app. Send them to any fab house.
• Component library editor: Add custom components with custom footprints and parameters. Save them for reuse.
• Multi-layer support: Up to 4 layers (top, bottom, and two inner layers) for complex boards.
• Measurement tools: Distance, angle, and area measurements right on the canvas. No need to guess.
• Project templates: Start from common board types (Arduino shield, breakout board, power supply) to speed up your workflow.
• Dark mode: Easy on the eyes during late-night debugging sessions.

Limited offer: the first 1,000 users get access to the premium component library expansion — normally a paid add-on — completely free. Today only. Grab Droid PCB and stop waiting for your desktop.

Heads up: You’ll need Wi-Fi for Gerber export and library updates. Some advanced simulation features require an in-app purchase. The free version includes 2-layer boards and up to 50 components per project.
