+ === LEDs
+
+ TeleGPS v1.0 has a dual greed/red LED along the edge
+ towards the USB connector end of the board. This
+ indicates battery charging status while connected to
+ power over USB. When the red LED is lit, the battery
+ is charging. Once the battery is fully charged, the
+ red LED goes out and the green LED turns on. If both
+ LEDs are lit, something is probably wrong with the battery.
+
+ TeleGPS v2.0 has the same green/red battery charging
+ status LED and adds another green LED along the same
+ edge, towards end of the board with the 70cm
+ antenna. This green LED indicates GPS lock status — it
+ blinks once every three seconds when the GPS receiver
+ is locked and tracking position.
