atmega4808 chip to multiplex serial/nmea0183 data - PaddyB - 2022-03-17
How do others get nmea0183 data into a raspberry pi?
I have too many usb/serial connections and need more.........
this chip looks interesting, 4 serial lines it says and low power, the system is on 24/7 on the boat so every mA counts...

Available from JLCPCB. The extra data I want isn't really time sensitive, victron solar controllers/smartshunts so reading from one device at a time isn't a problem.
Tempting to get some boards made by jlcpcb using those chips but any experience of either those chips or another low power way to get multiple serial into a Pi would be very interesting, ta.

Very interesting. And useful, thanks.
