Rs-485 Hub Smd
My old Rs-485 hub was getting to small to connect all the device from my Joshua domotica.
Designed a new one with smd components to reduce the size.
The line drivers SN75176 are still dip-8 to change them easy when there’s one broken, not that they ever breakdown (last 10 years zero) but you never know.
It’s stack able for extending the ports.

How much does the system cost if I buy it from you?
Thank you
Hi,
I’m sorry but they are (not anymore) for sale.
Hi I’ve been looking at your schematic and I’m wondering if it makes a difference on which port I use with master and what is rxen jumper used for?
Hi,
It doesn’t matter what port you use for the master, that’s why it’s a hub.
With the RXEN you can block for that port incoming data from the slaves on the section.
