Questions
How big is the EIM PCB?
It measures 170.6 × 121.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EIM use?
232 parts, built around the SN65HVD233D, ISL3172EIBZ, TLIN1027DRQ1 and AP63203WU. 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 EIM KiCad files?
From the bhorst519/bluecar repository on GitHub, at the commit this page was made from: the board is EIM/pcb/EIM/EIM.kicad_pcb and its schematic EIM/pcb/EIM/CAN_transceiver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the EIM design in my own project?
Its repository states no licence, so its author keeps all rights: ask bhorst519 before reusing the design.
