Can this be used to add RS232 to a Pi?
You mention using this with the Serial Hat to connect to a PC. What I'm looking for is a way of connecting 3 RS232 devices to a Pi. Would 3 of these do the job?

  • Ah sorry I see what you mean now! I've just tested it and yes, you can plug this into the USB port of the Pi and attach your serial device that way.

  • So this can't be used for adding an RS232 connection to a Pi by plugging it into the Pi USB port and a serial device into that?

  • The Raspberry Pi only has 1 UART port, and so only 1 serial device can be used with the Pi at any one time.
