Questions
How big is the FreeDSP SMD AB plus PCB?
It measures 134 × 109.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the FreeDSP SMD AB plus use?
233 parts, built around the LME49720NA, 24AA256-E/P, 2SC3326-A and AO3400A. 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 FreeDSP SMD AB plus KiCad files?
From the CyberPit/FreeDSP_Classic_SMD_AB_plus-II repository on GitHub, at the commit this page was made from: the board is KICAD/FreeDSP_SMD_AB_plus.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the FreeDSP SMD AB plus design in my own project?
Its repository states no licence, so its author keeps all rights: ask CyberPit before reusing the design.
