Questions
How big is the Mu ltz PCB?
It measures 34.5 × 56 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mu ltz use?
46 parts, built around the AD8667ARZ, ADA4523-1BRZ, LTZ1000ACH and 2SD1628G-TD-E. 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 Mu ltz KiCad files?
From the marcoreps/LTZmu repository on GitHub, at the commit this page was made from: the board is mu-ltz.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mu ltz design in my own project?
Its repository states no licence, so its author keeps all rights: ask marcoreps before reusing the design.
