Questions
How big is the AQ25027-Meerya Speaker RevB PCB?
It measures 144.8 × 73 mm and has 6 copper layers, 1.6 mm thick.
What parts does the AQ25027-Meerya Speaker RevB use?
155 parts, built around the AP2112K-1.8TRG1, AP2112K-3.3TRG1, CMM-3125AT-42316-TR and MMBT2222A-TP. 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 AQ25027-Meerya Speaker RevB KiCad files?
From the dcmcshan/meerya-dev repository on GitHub, at the commit this page was made from: the board is meerya/AQ25027_Meerya_Speaker_RevB/AQ25027-Meerya-Speaker-RevB/AQ25027-Meerya-Speaker-RevB.kicad_pcb and its schematic meerya/AQ25027_Meerya_Speaker_RevB/AQ25027-Meerya-Speaker-RevB/AQ25027-Meerya-Speaker-RevB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AQ25027-Meerya Speaker RevB design in my own project?
Its repository states no licence, so its author keeps all rights: ask dcmcshan before reusing the design.
