PCB Toolkit

PCB Toolkit is a fast, accurate electronics calculator and reference for PCB designers and hardware engineers. Use it to size traces, plan stackups, and verify impedance for high speed and power designs. Key features include impedance and differential pair calculators with material presets, trace width and via current based on industry data, and a stackup planner with layer and dielectric parameters. Advantages include instant results as you type, unit conversion and bookmarks, and offline access to essential reference tables. Ideal for PCB design, EDA workflows, and signal integrity checks.
