Questions
How big is the Amp module PCB?
It measures 80 × 22 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Amp module use?
26 parts, built around the TPA3221DDVR. 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 Amp module KiCad files?
From the KyGuy2002/ProjectDMX-PCB repository on GitHub, at the commit this page was made from: the board is amp-module/amp-module.kicad_pcb and its schematic amp-module/amp-module.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Amp module design in my own project?
Its repository states no licence, so its author keeps all rights: ask KyGuy2002 before reusing the design.
