Questions
How big is the 1802-Mini SPI DMA PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 1802-Mini SPI DMA use?
44 parts, built around the 74HC00D, 74HC04D, 74HC10D and 74HC02. 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 1802-Mini SPI DMA KiCad files?
From the arhefner/1802-Mini-SPI-DMA repository on GitHub, at the commit this page was made from: the board is 1802-Mini-SPI-DMA.kicad_pcb and its schematic 1802-Mini-SPI-DMA.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 1802-Mini SPI DMA design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
