Questions
How big is the AL8843 PCB?
It measures 42.1 × 24.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AL8843 use?
18 parts, built around the AL8843SP, CL21B105KBFNNNG, UMK316AB7475KL-T and B360B-13-F(MS). 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 AL8843 KiCad files?
From the ealex/AL8843 repository on GitHub, at the commit this page was made from: the board is hardware/al8843/al8843.kicad_pcb and its schematic hardware/al8843/al8843.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AL8843 design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
