Questions
How big is the Nucleo DAQ Shield PCB?
It measures 53.3 × 78.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Nucleo DAQ Shield use?
36 parts, built around the DRV8871DDA, LMV722M, LM1117-5.0 and TLV70233DBV. 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 Nucleo DAQ Shield KiCad files?
From the Yarulik/Nucleo_DAQ_Shield repository on GitHub, at the commit this page was made from: the board is Nucleo_DAQ_Shield.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Nucleo DAQ Shield design in my own project?
Its repository states no licence, so its author keeps all rights: ask Yarulik before reusing the design.
