Where would I find more information on setting the 31250-baud rate on the Pi?

Re: Two serial devices

If you don't need to talk to both devices simultaneously try multiplexing the serial interface using two MAX3232 buffers and a 4052 multiplexer

ie.

loop start
switch mux to OBD-II
read OBD-II data
do something with OBD-II data
switch mux to GPS
read GPS data
do something with GPS data
loop end

Re: Raspberry Pi HATs - SSR Hat?

Theres a list of sorts for add-on boards on the wiki, but I'm not sure how many add-on boards are HAT specific. Designing a SSR HAT would be pretty straight forward, SSR modules are pretty easy to work with but I would have serious safety concerns about switching potential lethal voltages (~230Vac) ...

Pleased to say my B+ arrived last week from CPC.

Looking forward to the using the extra GPIO signals and having 4x mounting holes for my boards.

Oh, and the extra USB's, better PSU, micro-SD and other improvements as well :-)

Re: RS 232 like signals on the GPIO pins?

I think the Palm Pilot serial interface was at RS232 levels and not TTL. I'm pretty sure they used a MAX3222 (or similar) transceiver chip internally. So you'll need a RS232 interface, some thing like this board: http://zuzebox.files.wordpress.com/2012/06/minipiio_rs232_small.jpg Here's a link to a ...
