Raspberry Pi 4 released!

there's more than one way to skin a cat
i have a few extra serial ports on a raspberry pi 3 now

 i picked up this for $10.00 on ebay

and a few of these

This is certainly one of the possible solutions to get around the lack of RIP 3 serial interfaces, but more connectors, more power supplies, and more cables often mean worse MTBF and MTTR.  

RIP 4 apparently has enough uarts to connect with the main NMEA183 devices that may possibly exist on the boat.  I'm trying to figure out how best to take advantage of this extra feature and simplify the installation and maintenance of the entire system.

 What do you guys think of a new HAT to address this?

Thank you.
