There is one thing that can make better de CI online build service.
M5stack don't sell a RS232/422 unit, but there is a lot of boards available on the market.
I use a YL-128 board to read and write nmea0183 signals, the board is TTL <--> RS422. I solder a groove cable to attach it directly to the M5 Atom.

Tested latest testci20240328 and works well. Able to read and write NMEA0183 data with real hardware.
Baud rate has to be selected in config to 4800 to match with the nmea standard.
I´ll make a PR with docs.
Thanks!
