Questions

How big is the Basic Stereo Amp PCB?

It measures 85 × 85 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Basic Stereo Amp use?

71 parts, built around the NE5532, 1N4148W and DMP6180SK3. 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 Basic Stereo Amp KiCad files?

From the halherta/KiCadProj repository on GitHub, at the commit this page was made from: the board is Basic Stereo Amp/Basic Stereo Amp.kicad_pcb and its schematic 16ChannelServoControllerDaughterboardDesign/16ChannelServoControllerDaughterboardDesign.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Basic Stereo Amp design in my own project?

Its repository states no licence, so its author keeps all rights: ask halherta before reusing the design.
