Questions
How big is the VCAI2C02 PCB?
It measures 70.6 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VCAI2C02 use?
43 parts, built around the ADUM3190ARQZ, MCP3423-E/UN, CDBHM260L-HF and MM5Z10VT1G. 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 VCAI2C02 KiCad files?
From the mlab-modules/VCAI2C02 repository on GitHub, at the commit this page was made from: the board is hw/sch_pcb/VCAI2C02.kicad_pcb and its schematic hw/sch_pcb/VCAI2C02.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the VCAI2C02 design in my own project?
Its repository states no licence, so its author keeps all rights: ask mlab-modules before reusing the design.
