Questions
How big is the Mini DSP PCB?
It measures 34 × 87.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Mini DSP use?
95 parts, built around the RP2350A, ES8388, W25Q128JVSIQ and AMS1117-3.3. 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 Mini DSP KiCad files?
From the kingovchouffe/Mini-DSP repository on GitHub, at the commit this page was made from: the board is HW/Main/Mini-DSP.kicad_pcb and its schematic HW/Main/Mini-DSP.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mini DSP design in my own project?
Its repository states no licence, so its author keeps all rights: ask kingovchouffe before reusing the design.
