· Try it

Change one part, see the verdict

Every swap is checked the moment you make it. Try it here with the simplest circuit there is.

Try a swap
A 5 V supply, a series resistor and a red LED. Choose a smaller resistor and watch the current climb.

Within limits. The LED draws 9.1 mA, comfortably under its 20 mA rating.

Simplified here with a fixed 2 V LED drop. The studio solves the full circuit.

· Verdicts

Every part passes three checks

A component only fits a slot when all three agree. If one fails, Echidna tells you which and by how much.

It connects

01

The interface matches: the right socket, connector and number of lanes.

It is powered

02

The slot’s rails can supply the voltage and current the part needs.

It stays cool

03

The heat it gives off fits the slot’s thermal budget and the cooling around it.

· Devices

Six kinds of device, one set of rules

Recreate a real device from a preset or start from a blank board. Each type has its own catalogue of swappable parts.

  • Smartphones

    iPhone and Galaxy presets

  • Desktop PCs

    Budget, gaming and workstation builds

  • Laptops

    Ultrabook and gaming presets

  • Drones

    DJI Mini series and 5-inch FPV

  • Dev boards

    Raspberry Pi, ESP32 and Arduino

  • Wearables

    Smartwatch and fitness band

· Data

Every number shows where it came from

Values are labelled as datasheet, teardown or estimate, so you know how far to trust a verdict. When a fail rests only on estimates, Echidna says it is likely to fail rather than certain.
