Questions
How big is the Rees amp PCB?
It measures 20.5 × 52.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rees amp use?
22 parts, built around the LM386. 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 Rees amp KiCad files?
From the Miceuz/piezo-preamp repository on GitHub, at the commit this page was made from: the board is rees-amp.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rees amp design in my own project?
Its repository states no licence, so its author keeps all rights: ask Miceuz before reusing the design.
