Questions
How big is the BalancedSurroundOut PCB?
It measures 45 × 62 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BalancedSurroundOut use?
68 parts, built around the DRV134UA, TLV75533PDBV, LM27762DSS and PCM5102PW. 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 BalancedSurroundOut KiCad files?
From the samo4/BalancedSurroundOut repository on GitHub, at the commit this page was made from: the board is hardware/BalancedSurroundOut.kicad_pcb and its schematic hardware/BalancedSurroundOut.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BalancedSurroundOut design in my own project?
Its repository states no licence, so its author keeps all rights: ask samo4 before reusing the design.
