Questions
How big is the AkaLinkCompact PCB?
It measures 45 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AkaLinkCompact use?
57 parts, built around the CH32V305FBP6, SN74LVC1T45DBV, TPS22918DBV and USBLC6-2SC6. 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 AkaLinkCompact KiCad files?
From the akkako/akaLinkCompact repository on GitHub, at the commit this page was made from: the board is hardware/HWVer_B.01/akaLinkCompact.kicad_pcb and its schematic hardware/HWVer_A.01/akaLinkCompact.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AkaLinkCompact design in my own project?
Its repository states no licence, so its author keeps all rights: ask akkako before reusing the design.
