Stop guessing wire lengths
Measure wires before soldering instead of trimming by trial and error at the bench.
Perfboard CAD Tool
PerfBoard is a free browser-based perfboard layout tool for electronics hobbyists, makers, and engineers. Place components on a virtual perfboard grid, route wires with Manhattan or diagonal paths, and export a cut sheet that shows wire lengths and cumulative bend points.
PerfBoard is built for people assembling one-off circuits, prototypes, and hobby electronics on perfboard. It is especially useful when you want cleaner wire routing, repeatable builds, and fewer bench-side mistakes.
Common use cases include synth modules, robotics control boards, test fixtures, educational electronics, and any perfboard build where wire length and bend accuracy matter.
Measure wires before soldering instead of trimming by trial and error at the bench.
Plan around pin headers, spacing limits, and board geometry before touching the iron.
Use solder-side and export views as a build reference when assembling or reviewing a layout.
PerfBoard is a free web app at perfboard.app. It helps users design perfboard layouts, route jumper wires, calculate exact cut lengths and bend points, and export build guides. The application runs in the browser and is intended for electronics makers, hobbyists, and engineers building circuits on perfboard or protoboard.
