About the site

Engineering without the black box.

Bits on Breadboard is a place for practical embedded engineering: the measurements, failed attempts, debugging steps, and design choices that often get left out of polished documentation.

The goal is simple—make complex hardware topics understandable without oversimplifying the engineering.
