Droid PCB

You are debugging a new prototype on a 4-layer board, but your laptop screen is too small to trace the power plane properly. You zoom in, zoom out, lose orientation, and waste ten minutes finding the via that connects pin 7 to the decoupling capacitor. There is a faster, more precise way to work with your PCB files on the go.

Droid PCB is a mobile circuit-board viewer and navigator designed for engineers, technicians, and hobbyists who need to inspect Gerber files, drill files, and netlists directly on an Android device. It transforms your phone or tablet into a portable inspection station, letting you pan, zoom, measure, and identify every component without opening a full EDA suite.

Core Capabilities

• Gerber & Drill File Rendering – Open RS-274X Gerber files and Excellon drill files with support for aperture definitions, flash commands, and polygon fill. The rendering engine processes complex copper layers, solder masks, silkscreens, and paste masks in real time.
• Layer-by-Layer Toggle – Independently enable or disable any layer (top copper, bottom copper, inner planes, top overlay, bottom overlay, solder mask, paste mask). Overlay multiple layers simultaneously with adjustable opacity to compare copper pour against silk legend.
• Precision Measurement Tool – Tap two points on the board to display the exact distance in millimeters or inches. The tool snaps to pad centers, via centers, and track endpoints, giving you dimension data without a separate caliper.
• Net & Component Highlighting – Load a netlist file to highlight all copper features belonging to a specific net. For example, select “VCC” and instantly see every pad, via, and track connected to the power rail. This is invaluable for trace-routing validation and short-circuit hunting.
• Coordinate & Stack-Up Viewer – Display absolute X/Y coordinates of any cursor position, plus the board outline dimensions. A built-in stack-up diagram shows the layer order and thickness, helping you verify impedance-controlled designs.

Key Advantages

• Offline Operation – All rendering and measurement happens locally on the device. No cloud uploads, no latency, no privacy risk for proprietary board designs.
• High-Resolution Pan & Zoom – The renderer uses multi-threaded bitmap caching to provide fluid 60-fps navigation even on boards with thousands of pads and complex copper regions.
• Multi-Format Import – Accepts .GTL, .GBL, .GTO, .GTS, .DRL, and many other Gerber/drill extensions. Also imports standard .NET and .TXT netlist files from Altium, Eagle, KiCad, and OrCAD.
• Dark & Light Mode – Switch between a high-contrast dark theme for on-site field work and a light theme for office use. Both modes preserve color accuracy for solder mask and copper differentiation.
• No Subscription Required – A single purchase unlocks the full feature set. No ads, no in-app paywalls for measurement tools or layer toggle count.

Download Droid PCB now and carry the full board inspection tool in your pocket. Stop switching between laptop and bench — start verifying traces, checking clearances, and measuring distances directly from your Android device.

Disclaimer: Droid PCB requires an internet connection only for initial license verification; all board file processing is performed offline on the device. The app contains no in-app purchases and no third-party advertising. Minimum supported Android version is 4.2 (Jelly Bean). Supported board file formats include Gerber RS-274X, Excellon drill files, and standard netlist (.net) files. The app does not provide PCB design or editing capabilities — it is a viewer and measurement tool only. Use of the measurement tool is subject to the accuracy of the imported file data; always verify critical dimensions against original design files.
