RS485: common questions

How big is the RS485 PCB?

The RS485 measures 33 × 22.9 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the RS485?

18 components, from 8 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the RS485 design files?

From the FYNCH-BIO/hardware repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the RS485 design in my own project?

The repository has no license, so all rights stay with FYNCH-BIO. Use it as a reference, and ask the author before reusing the design.
