Hi,
I have an upcoming project where I have to capture data from 2 rs232 devices, temporarily (for a month or so and can then be overwritten) save that data (probably to an sd card) and then output that same data on 2 more rs232 ports.
So I need 4 rs232 ports, a suitable microprocessor board and a suitable storage solution.
I have previously played successfully with a Metro M4 Express AirLift, so I'm considering another of these, but all suggestions welcome. If the hardware can be sourced within the UK that would be a bonus.
cheers
Alex

Have you considered the Grand Central M4? It comes with the Micro SD card slot already there. It also has 8 serial ports (SERCOM).

Re: Hardware suggestions please
The M4 suggested above would be a good choice .
Note that the serial ports on microcontrollers in general are TTL serial. RS232 uses inverted logic and a higher signal voltage. To communicate with RS232 serial devices you will need an RS232 to TTL converter. SeeedStudio makes a nice one:
