Hello Tim,

I think this will work out well for you!  The MAX232 and EEPROM are included but they are optional.

When they are installed they connect to port A.  RA.0 and RA.1 are normally used for the EEPROM at loation U2.  The pins are clearly marked on the silkscreen if you want to use them for something else.  RA.2 is normally used as a Serial in (RX) and RA.3 as Serial out (TX) via the MAX232.  They work great with the serial commands in SX/B.

All the other ports B, C, D, and E are brought out to the DIP headers and are clearly marked.  The docs should cover everything pretty well and the schematics are included.  I'll be glad to answer any questions about the kit that come up.

Best Regards,

Robert
