Hello,I would like to ask you some questions about the Serial Pi Plus.I am willing to try but iI would need more than one RS-232 port on my board.- May I plug another Serial Pi Plus over one Serial Pi Plus plugged into a raspberry ?- Will I be able to read/write on each other port ?- Would it work on any raspberry which can handle one Serial Pi Plus already ?Thank you for your time and have a nice day.

Unfortunately, you can only use a single Serial Pi Plus board on a Raspberry Pi as the Pi only has a single UART port on the GPIO header.

If you need additional RS232 ports you will need to use a USB-Serial adapter.
