 - can I put the GPS chip antenna on the board *and* allow for an SMA or other
   connector if we want it off-board?
 
+- changing the memory part from the SOIJ8 to the DFN8 would save about 2mm
+  in width, but that doesn't really help.
+- changing the 5V switcher from S8 to MS8 takes us from 5 tall to 3 tall, but
+  costs $0.30 more per piece and isn't stocked by Digikey.  Not worth it?
+
+- noticed the NXP SC18IS600, which is an SPI slave to I2C master interface
+  with a few GPIO lines...  mate that with an HMC5843, which is a 3-axis
+  magnetic sensor, and we might have another interesting companion board for TM

 - To Do List
 
        - add serial connector back to schematic as optionally loaded part
        - move USB connector on PCB layout 80 mils in from board edge
-       - create PCB footprints for the GPS module and GPS antenna
+               - move yellow LED and passives closer to LiPo connector
+       + create PCB footprint for the GPS module 
+       + create PCB footprint for the GPS antenna
