Why Use PCB Tools?
They can help you make your work easier, find mistakes early, and get accurate results. Whether you build prototypes at home or make a commercial product, our fast and simple calculators help you design with confidence and save time.
Key Benefits
Adjusting trace width makes sure your board can handle the right amount of current and stops hot spots. Decoding SMD resistor marks changes tiny codes into exact resistance values and removes guessing. Choosing the right LED resistors protects your LEDs from too much current, making them brighter and last longer.
PCB designers who want to make fewer changes by planning carefully. Electronics hobbyists who want easy calculations for personal projects. Engineers who need quick checks during development. Students who learn PCB basics with real examples.
Use our all-in-one calculator suite to make your next PCB project better. It helps you make smarter, faster, and fewer mistakes in your designs.
