Questions

How big is the SD Tape Player PCB?

It measures 62.5 × 67 mm and has 2 copper layers, 1.6 mm thick.

What parts does the SD Tape Player use?

36 parts, built around the 74LVC125AD, LM386 and B3F-3100. 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 SD Tape Player KiCad files?

From the GadgetReboot/SD_Tape_Player repository on GitHub, at the commit this page was made from: the board is KiCad/SD_Tape_Player.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the SD Tape Player design in my own project?

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