Questions
How big is the Wesp card access PCB?
It measures 75 × 40 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Wesp card access use?
70 parts, built around the MAX3485ED, RS485 and ADS7828E. 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 Wesp card access KiCad files?
From the Technocopia/WESP_PoE_Door_entry repository on GitHub, at the commit this page was made from: the board is wesp_card_access.kicad_pcb and its schematic wesp_card_access.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wesp card access design in my own project?
Its repository states no licence, so its author keeps all rights: ask Technocopia before reusing the design.
