+== Technical Information
+
+ === GPS Receiver
+
+ TeleGPS uses the u-Blox Max-7Q GPS receiver.
+
+ === Micro-controller
+
+ TeleGPS uses an NXP LPC11U14 micro-controller. This
+ tiny CPU contains 32kB of flash for the application
+ and 4kB of RAM for temporary data storage.
+
+ === Lithium Polymer Battery
+
+ Shipping restrictions may prevent us from including a
+ battery battery with TeleGPS.
+
+ === Mechanical Considerations
+
+ TeleGPS is designed to be rugged enough for typical
+ rocketry applications. The 4 mounting holes on the
+ board are sized for use with 4-40 or M3 screws.
+
+ === On-board data storage
+
+ TeleGPS has 2MB of non-volatile storage, separate from
+ the code storage memory. The TeleGPS firmware uses
+ this to log information during flight.
