Questions
How big is the Preamplifier with PS PCB?
It measures 59.5 × 49.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Preamplifier with PS use?
11 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 Preamplifier with PS KiCad files?
From the chdsolinap/ece-projects repository on GitHub, at the commit this page was made from: the board is Public Address System (Audio Amplifier)/Preamplifier_Power_Supply/preamplifier_with_PS.kicad_pcb and its schematic 4-bit Full Adder/4_bit_full_adder_pcb.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Preamplifier with PS design in my own project?
Its repository states no licence, so its author keeps all rights: ask chdsolinap before reusing the design.
