● Runs on your device; nothing is uploaded

How to use it

  1. Choose External layer or Internal layer.
  2. Enter the Current (A) and allowed Temperature rise (°C).
  3. Pick the Copper weight and set the Ambient temperature.
  4. Add a Trace length (mm) to see resistance, voltage drop and power loss.
