Questions

How big is the Rs485-uart PCB?

It measures 40 × 20 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Rs485-uart use?

8 parts, built around the ISL83490IBZ-T. 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 Rs485-uart KiCad files?

From the Novakov/rs485-uart repository on GitHub, at the commit this page was made from: the board is rs485-uart.kicad_pcb and its schematic rs485-uart.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Rs485-uart design in my own project?

Its repository states no licence, so its author keeps all rights: ask Novakov before reusing the design.
