Questions
How big is the AkaLinkPro PCB?
It measures 45 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AkaLinkPro use?
95 parts, built around the HPM5301IEG1, LMV321, SN74LVC1T45DBV and TPS22918DBV. 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 AkaLinkPro KiCad files?
From the akkako/akaLinkPro repository on GitHub, at the commit this page was made from: the board is hardware_pro/akaLinkPro.kicad_pcb and its schematic hardware/akaLinkPro.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AkaLinkPro design in my own project?
Its repository publishes it under the Apache-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
