Questions
How big is the TTLtoCANforTOF PCB?
It measures 33.5 × 17.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TTLtoCANforTOF use?
44 parts, built around the TCAN3413DRB, TD1469, ME6211C33M5G-N and BZT52C12S. 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 TTLtoCANforTOF KiCad files?
From the QDU-Robomaster/TTLtoCAN repository on GitHub, at the commit this page was made from: the board is TTLtoCANforTOF.kicad_pcb and its schematic TTLtoCANforTOF.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TTLtoCANforTOF design in my own project?
Its repository states no licence, so its author keeps all rights: ask QDU-Robomaster before reusing the design.
