Brief Introduction of GPS demo board
Product
Figure 1 Produce (Top View)
1. Great for GPS based tools or appliance development.
2. Three useable ports, USB->UART Bridge based on CP2102, legacy RS232 port, and
an optional Bluetooth simulated RS232 port.
3. Module compatible with Ublx TIM-LC module in pin out.
4. Module use uNav 8130 baseband processor, 1008 RF frontend, 4th generation,
-152dbm sensitivity.
5. Low power consumption

6. Could locate with the antenna inside the room and 1 meter away from the window
(normally when over 6 satellites in view site).
7. Orion Analyzer software and U-Center software provided, Baud rate, NMEA output
package selectable. (GPS module baud rate is constant 9600bps.)
8. Pulse per second signal selectable. (Not in the standard Rom, could be flashed into the
module, we would not provide any warranty if the module failed in update.)
9. All 3 communication method could work together. All 3 ports could control the module
and accept NMEA data.
10. USB port and Bluetooth port can not modify the baud rate, user can only modify
NMEA output package through those 2 ports.
11. Through RS232 port, all parameters could be modified.
12. Update may cause module fail permanently, and will cause warranty void. If user
wants to do update, user must use a RS232 port (not USB bridged type) to update firmware.

1．Connect the SMA connector of the Active antenna to the demo board and tie the screw
(Shown in Figure 1). Put the antenna to outdoor and keep the top side face the sky. The
antenna has integrated magnet, so it can be magnetized on any iron surface such like roof of
your car. Try to place it with a large viewable angle of the sky, if covering with any metal
material, the signal would be weak.
You could only use 3.3V type active antenna with this demo board, 5V active antenna will
not work. Keep the top of the antenna face the sky, or the signal may be too weak. Most active
antennas are anti water type, they could work in raining days.
2. Connect the USB->UART Bridge based on CP2102 to your host computer with the
USB connector. And tie miniusb to the demo board. Power on your host computer and install
the driver.
This GPS module is compatible with NMEA2.1 protocol, so it could work with most GPS
software which will accept NMEA protocol. For testing use, you could find Orion Analyzer
software and u-center evaluation software in the accessory CD. It is only for testing and
studying use. We do not provide any support on how to use Orion Analyzer or u-center, please
view the user’s guide from Orion Analyzer and u-center carefully. And notice don’t try update
firmware with Orion Analyzer or u-center, it may damage your module.
Your demo board should work after those steps, if you have any further questions, please
read the schematic and user’s guide carefully, and you could also email to
[email protected], we will try to solve all questions.
