Point your phone at a circuit board. Know the parts on it.

CircuitLens finds the components in the photo, reads their markings and draws how the parts connect. On your phone or your computer, in six languages.

Launch offer until 17 November: 10 free analyses, then 1 free analysis every week.

From a photo to a schematic

Look around without an account: every tool and a sample analysis are open to everyone. Sign in to analyze your own boards and keep them.

  1. A technician photographs a circuit board with a phone on a workbench

    Take a photo

    Lay the board flat, fill the frame and avoid flash glare, so the markings stay readable.

  2. Close-up of a resistor marked 103 next to a small transistor and a capacitor

    Every part, named

    Each part gets its type, its marking, a likely part number and its package.

    The schematic, drawn

    An approximate schematic of how the parts connect, which you can export to KiCad. Then ask questions about the board in plain words.

Made for the bench and the classroom

Repair technicians, students and makers use it for different reasons.

Find the part that failed

A bulging capacitor or a burnt resistor: know what it is and look up a replacement before you desolder anything.

A breadboard, an Arduino board and a hand-drawn schematic on a desk

Understand the board in front of you

Pinouts, reference sheets and short quizzes for the parts you find, so the next board is easier.
