Questions
What parts does the VeraLink RevA2 use?
55 parts, built around the NRF52840-QIAA-R, DRV2605LDGS and TPS78233DDCR. 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 VeraLink RevA2 KiCad files?
From the ec1066/VeraLink-Hardware repository on GitHub, at the commit this page was made from: the board is hardware/RevA2/VeraLink_RevA2.kicad_pcb and its schematic hardware/RevA2/VeraLink_RevA2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the VeraLink RevA2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask ec1066 before reusing the design.
