Questions
How big is the Axis V2 PCB?
It measures 120 × 60 mm and has 2 copper layers, 1 mm thick.
What parts does the Axis V2 use?
53 parts, built around the MAX31855EASA+T, PCA9544AD, TCA9534PW and DS3231MZ/V+. 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 Axis V2 KiCad files?
From the Meigs2/Axis repository on GitHub, at the commit this page was made from: the board is hardware/pcbs/Axis_V2/Axis_V2.kicad_pcb and its schematic hardware/pcbs/Axis_Base_Rev01/Axis_Base_Rev01.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Axis V2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Meigs2 before reusing the design.
