Questions

How big is the BeamBender PCB?

It measures 50 × 100 mm and has 4 copper layers, 1.6 mm thick.

What parts does the BeamBender use?

104 parts, built around the AK5720VT, SII9022ACNU, LM1117-3.3 and SP1003-01DTG. 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 BeamBender KiCad files?

From the jbilander/BeamBender repository on GitHub, at the commit this page was made from: the board is KiCad/A1200-A500/BeamBender.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the BeamBender design in my own project?

Its repository publishes it under the CC-BY-SA-4.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
