Questions
How big is the Mic dual circuit PCB?
It measures 14.3 × 160 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Mic dual circuit use?
7 parts. 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 Mic dual circuit KiCad files?
From the kevmck451/line_array repository on GitHub, at the commit this page was made from: the board is Circuit_Board/mic_dual_circuit/mic_dual_circuit.kicad_pcb and its schematic Circuit_Board/mic_dual_circuit/mic_dual_circuit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mic dual circuit design in my own project?
Its repository states no licence, so its author keeps all rights: ask kevmck451 before reusing the design.
