Questions
How big is the Rm controller hardware PCB?
It measures 90 × 65 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rm controller hardware use?
49 parts, built around the TJA1441AT/0Z, BU33SD5WG-TR, SM02B-GHS-TB and RJ45. 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 Rm controller hardware KiCad files?
From the nityc-d-robo/rm_controller_hardware repository on GitHub, at the commit this page was made from: the board is rm_controller_hardware.kicad_pcb and its schematic CAN_Transceiver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rm controller hardware design in my own project?
Its repository states no licence, so its author keeps all rights: ask nityc-d-robo before reusing the design.
