I'm thinking this is the correct orientation for the microSD - the vertical lines to the right are part of the microsd symbol. No idea what they do besides get in the way.
Rob,
I had an e-mail typed up & it got dumped while I was looking up a 4 pin header to stick on the 4-pin RS232 header. I think I will recommend folks use 4-pin crimp connector housing that pololu.com carries, 3 wires plug in, the other ends connect to uses RS232 connector of choice. Just occurred to me - what if I made that 3 pins with ground in the middle? Then the housing could be plugged on either way, worst case Tx goes against TX and nothing gets received on either end.
I've had no luck finding a 2x2 crimp on type for a ribbon cable.
Reset_enable - 3 pin header was used as I couldn't find a 2 pin header that was just pins.
Values - I left off the R & C values, are just 1K/10K resistors, 100nf/0.1uF for the small caps, 100uF for the 3 big one, nothing unusual.
COMM1 jumper - my intent there was to have jumpers across 1-2 and 3-4 to have RS232 going off board, and to have No jumpers installed if one needed D2/D3 not interfered with on the shield header.
I'm up for changing it to something that will provide more functionality, I don't understand what you are referring to by Serial Polarity tho.
