I’m trying to find more information about the board shown in that part of the picture.  
I came across a forum post suggesting that this information used to be available on the FYNCHBIO website, but it seems the page is no longer accessible. That’s why I’m reaching out with this inquiry.

Hi JinHyeongKim,

I’ve added a wiki [page](https://khalil-lab.gitbook.io/evolver/hardware/motherboard-layout-and-circuitry/rs485-board) for the RS485 board. It should be a good place to start. Hopefully others who know more can fill it in a bit more @danhart @ezirayw @bgwong

@JinHyeongKim what aspect of the board are you interested in (design files, high-level explanation of what it does, etc)?

I needed a circuit diagram of the board and a pcb file.  
Thanks to your posting on GitHub, it’s resolved. Thank you.
