Questions
How big is the DSP Stamp Mini PCB?
It measures 39 × 54 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DSP Stamp Mini use?
71 parts, built around the PCM3060PW, W25Q128JVSIQ, ABM8-272-T3 and SM03B-SRSS-TB. 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 DSP Stamp Mini KiCad files?
From the JackUlbrichBaker/RP_Mini_Dsp repository on GitHub, at the commit this page was made from: the board is hardware/DSP_Stamp_Mini.kicad_pcb and its schematic hardware/DSP_Stamp_Mini.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DSP Stamp Mini design in my own project?
Its repository states no licence, so its author keeps all rights: ask JackUlbrichBaker before reusing the design.
