Introduction¶

dePCB.org project aims at helping people reverse engineer unknown electronic equipment faster and more easily.

We plan to provide a collaborative platform where people can identify components, IC, annotate parts of a PCB and discuss a probable use or receive suggestions about further enquiry (JTAG, UART serial, glitching, ...).

Use case #1¶

1. Upload image to depcb.org
2. OCR the image to retrieve any text (and display it on the web page, next to the image)
3. Position on the image where each text portion was recognized
4. Query an IC DB to fetch IC function / characteristics.

Spike tests¶

All the tests done to figure out the proper tools & architecture.

Test samples: http://depcb.org/sample-pix/

OCR tests with Ocropus¶

• This software is dedicated for book scanning and doesn't mix well with bad / chaotic pictures.
• Maybe the underlying Tesseract could be used for this.
