Copper Sketch Pro

A simple PCB layout tool for your Android device. Draw traces with your finger and they automatically snap to standard PCB routing angles (0°, 45°, 90°). Place pads, IC footprints, and passive component pins from a built-in library. Features: Freehand drawing that auto-straightens to PCB routing angles Component library with DIP ICs (8 to 40 pin), resistors, capacitors, diodes, transistors, connectors, and more Configurable trace width and pad size in mm Place, move, rotate, and delete components Add text labels and net names to pads Snap-to-grid for precise placement Pinch to zoom, pan to navigate Multi-select with drag rectangle to move groups Measurement tool to check distances between points Design Rule Check (DRC) for trace clearance and unconnected pads Export board as transparent PNG with copper-colored traces Save and load designs as JSON files Configurable board size (10mm to 500mm) Classic PCB green color scheme No account required. No internet needed. No ads in the design canvas. Useful for prototyping simple boards, planning perfboard layouts, or sketching PCB ideas on the go.
