Questions
How big is the CaesarV2 PCB?
It measures 103.5 × 85 mm and has 4 copper layers, 1.61 mm thick.
What parts does the CaesarV2 use?
155 parts, built around the ATSAM4E8CA-CU, LAN8741A-EN, SKY66112-11 and LDL1117S33R. 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 CaesarV2 KiCad files?
From the luhbots/luhsoccer_electronics repository on GitHub, at the commit this page was made from: the board is Caesar/CaesarV2.kicad_pcb and its schematic Asterix/ControlUnit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CaesarV2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask luhbots before reusing the design.
