Questions
How big is the Esp32-eth relay hat PCB?
It measures 72.8 × 21 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32-eth relay hat use?
24 parts, built around the MCP1415-E/OT, BC846, 2N7002L and MDB10S. 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 Esp32-eth relay hat KiCad files?
From the zopieux/makerspace repository on GitHub, at the commit this page was made from: the board is esp32-eth-relay-hat/esp32-eth-relay-hat.kicad_pcb and its schematic esp32-eth-relay-hat/current_sense.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32-eth relay hat design in my own project?
Its repository states no licence, so its author keeps all rights: ask zopieux before reusing the design.
