Questions
How big is the CarCANdy PCB PCB?
It measures 110 × 68 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CarCANdy PCB use?
85 parts, built around the SN65HVD233DR-JSM, TEENSY 4.1, LTV-357T and 1N4148W. 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 CarCANdy PCB KiCad files?
From the redt1de/CarCANdy repository on GitHub, at the commit this page was made from: the board is Hardware/CarCANdy-PCB/CarCANdy-PCB.kicad_pcb and its schematic Hardware/CarCANdy-PCB-v2/CarCANdy-PCB-V2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CarCANdy PCB design in my own project?
Its repository states no licence, so its author keeps all rights: ask redt1de before reusing the design.
