Yes, that would be my thought, too. I don't
particularly care about the
extra RAM, but having Ethernet is a must (for me). Actually,
While only yhr Model B Rpi has on-board ethernet, I am pretty sure it's a
USB to tthernet device hung off a USB port on the SoaC. I am also prtty
sure you can sue a USB ethernet thingy with a mdoel A if you want to
I can't remember now; does the 'Pi have RS232
built in (poss. with the
addition of external line drivers)?
To be pedantic, no. TO be practical, yes.
There is an asynchronosu serial port on 2 pins of the GPIO connecotr.
It's not RS232, it's 3.3V logic levels. But you can easily buffer it
(MAX3232 IC) to RS232 levels. The Rpi can use that as a serial console
too. By default it runs at 15200 baud (something which is very PC
speciifc, nd a ridiculous choice fothe default), but you cna set it to
just about any seped in one of the oconfiguration files.
