I will look more into this...the Micro is very interesting as being a
module rather than a board like the Uno, it would be more cost-effective
to build the Micro into a project versus the Uno.
I assume that the USB programming port is also the serial.print output
port to the serial monitor window? That seems to be the case, as the
technical description says:
"Serial: 0 (RX) and 1 (TX). Used to receive (RX) and transmit (TX) TTL
serial data using theATmega32U4 hardware serial capability. Note that on
the Leonardo, the Serial class refers to USB (CDC) communication; for
TTL serial on pins 0 and 1, use the Serial1 class."

Thank you for the link to this library. The TruePosition units use
their own communication method rather than NMEA, but the ability to
convert GPS seconds into date/time is very interesting and I will look
into this more. :)
thanks much,
