Appendix C. Technical Information
C.1. GPS Receiver
TeleGPS uses the u-Blox Max-7Q GPS receiver.
C.2. 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.
C.3. Lithium Polymer Battery
Shipping restrictions may prevent us from including a battery battery with TeleGPS.
C.4. 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.
C.5. 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.
