After pouring through all your comments here and in several other forums I'm getting very near to the final specification before I begin drawing the schematic.
I've settled on a main MPU (PIC32MX695F512H) and most of the I/O options.
1 Ethernet
1 XBee S2 (ZigBee)
2 DE9 serial ports DTE (1 RS485,422,232. programmable to 5 ports by double duty, the CTS/RTS & DTR/DSR pins can be made RX/TX pins!)
3 Relays (1 NO/NC, 2 NO)
1 RTCC with trickle charger (DS1388)
Suggestions needed on
SD card or micro SD mounted internally or 256kB of SPI EEPROM?
Four 1/8" stereo jacks with various I/O from IR out, IR in, GPIO, analog, 1wire. Making it versatile as it's technically eight I/O lines (two per jack) all under control of a secondary PIC. I'm trying to keep it from getting jumper happy so I'd appreciate your comments on what you'd like to see with four 1/8" phone jacks. If I left something out do tell.
PS name suggestions also appreciated. Magnus One? DUCK?
