Just an early block diagram with some ideas. I plan a backbone bus with Power, Control, Data and Address pins. No MCU on the backbone, but should be clickable into PSU modules at each end + be extendable by 4+4+4…
A motheboard with Ethernet, Wifi as a GW to normal network using the same form-factor as a sub-board – Can also act as a stand-alone RS-X gateway. One of the PSU units can be a battery etc. Many nice options here, but need to play around With ideas for a while.
The bus will probably contain
- 4 x Serial (RS-X)
