Questions
How big is the PICO RS485 PCB?
It measures 80 × 80 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PICO RS485 use?
61 parts, built around the THVD1406DRL, SHT31-DIS-F, 0ZCF0100AF2A and 1N5819HW-7-F-01. 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 PICO RS485 KiCad files?
From the mortens-lab/PICO_RS485 repository on GitHub, at the commit this page was made from: the board is PICO-RS485.kicad_pcb and its schematic PICO-RS485.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PICO RS485 design in my own project?
Its repository states no licence, so its author keeps all rights: ask mortens-lab before reusing the design.
