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.
