Questions
How big is the DAQHat Rev A PCB?
It measures 65 × 56.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the DAQHat Rev A use?
36 parts, built around the RA73F2A1K0BTD, PHP00805E4990BST1 and ADE0804. 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 DAQHat Rev A KiCad files?
From the xwlred/H-HAT repository on GitHub, at the commit this page was made from: the board is DAQHat Rev A.kicad_pcb and its schematic DAQHat Rev A.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DAQHat Rev A design in my own project?
Its repository states no licence, so its author keeps all rights: ask xwlred before reusing the design.
