Questions
How big is the CAN Eth Bridge PCB?
It measures 22.6 × 60.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the CAN Eth Bridge use?
59 parts, built around the TPSM33606S5QRDNRQ1, W5500, MMBT5550L and MH1608-151Y. 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 CAN Eth Bridge KiCad files?
From the Gregification/BeeMS repository on GitHub, at the commit this page was made from: the board is hardware/CAN_Eth_Bridge/CAN_Eth_Bridge.kicad_pcb and its schematic hardware/CAN DC SS switch/CAN DC SS switch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CAN Eth Bridge design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
