Questions

How big is the BoHansen DI PCB?

It measures 50 × 75 mm and has 2 copper layers, 1.6 mm thick.

What parts does the BoHansen DI use?

37 parts, built around the BC550 and BC560. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the BoHansen DI KiCad files?

From the markthompson117/BoHansenPCB repository on GitHub, at the commit this page was made from: the board is BoHansen_DI.kicad_pcb and its schematic BoHansen_DI.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the BoHansen DI design in my own project?

Its repository states no licence, so its author keeps all rights: ask markthompson117 before reusing the design.
