Questions

How big is the Mixer PCB?

It measures 110.5 × 114.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Mixer use?

101 parts, built around the 74HC240D, LB1938FA-BH and PCA9615DP. 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 Mixer KiCad files?

From the arneman44/Mixer repository on GitHub, at the commit this page was made from: the board is Mixer PCB/kicad/mixer board/mixer.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Mixer design in my own project?

Its repository states no licence, so its author keeps all rights: ask arneman44 before reusing the design.
