Questions
How big is the STM32NGFF PCB?
It measures 64.9 × 38.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the STM32NGFF use?
41 parts, built around the 74LVC1G17Z, MIC5205-3.3YM5, USBLC6-2SC6 and S4B-PH-K-S(LF)(SN). 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 STM32NGFF KiCad files?
From the cyberknet/STM32NGFF repository on GitHub, at the commit this page was made from: the board is STM32NGFF.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the STM32NGFF design in my own project?
Its repository states no licence, so its author keeps all rights: ask cyberknet before reusing the design.
