SteenosMT Posted February 19, 2020 Share Posted February 19, 2020 Hey bud. I watched your video At 47 minutes into your video you talk about building your hub. Pretty detailed work. But for me being a non engineer, I have no idea how this works. I've gotten some PCB's made for the nanos to accept a max 487 and to be daisy chained via network. There's two network connectors on the board. But I will still need to be able to deliver 5v to all of the boards as well. Just curious if you had any more insight on how to get started. Thanks!

CraigS Posted February 19, 2020 Share Posted February 19, 2020 Hi SteenosMT, I think the starting point is to find a schematic that outlines the minimum requirements of an RS485 network. To then create that using breadboard and components, and run test after test until it works and you are comfortable with it. When I started, my initial point of reference was the post below created by Hansolo. https://forums.eagle.ru/showthread.php?t=243611 His post is a great guide to creating this network. I would review this post and by all means combine it with my YouTube video. At 32 minutes I talk through the minimum setup. This covers an explanation of the distribution of power throughout the network. I also put some diagrams on my website based on what I did (link below) https://mysimpit.co.uk/front-dash/ When your tests progress from trying to get it to work without breaking it, to intentionally trying to see what will break it, you are likely ready to create that setup and implement into your simpit. Hope that helps, cheers Sent from my SM-N975F using Tapatalk Link to comment Share on other sites More sharing options...

Middlefart Posted February 21, 2020 Share Posted February 21, 2020 (edited) Max 487 Hub, Question for Craig S SteenosMT since you are using the my boards you can’t wire the RJ45 exactly as CraigS did. You need to follow the pinout I put in the Dropbox folder and/or using the diagram I sent you in Slack. It will not work otherwise.
