hi guys
I just recieved two xbee pro modules and a droids usb adapter with a simple xbee board, i also got the "ls2003" gsp module.
Integration was as follows.
1.split the included 90 degree header in to four two segment units
2. solder the header two the usb board at the rx/tx port and the 3.3 volt ports.
3. solder the headers to the simple board at the rx/tx inputs and the 3.3 and ground
4. solder a nine volt clip / battery holder to the simple board at vin and gnd
5. take the cable that came with the ls20033, raid an old computer for the cables with the molex connectors on the end two strand is what you need. connect pins 1+6 to the positive and pin 2 to the gnd. connect pins 3+ 4 to the rx/tx.
6.put the solder iron away
7. plug the gps unit into the usb board/ the nice thing about this board it has pin out fo ttl level serial and 3.3 voltage
8. install the driver for the ubs board, see droids.it for the redirect. on my machine it installed a microsoft mouse drive that i had to disable in the control panel. Now your computer should talk to the usb module.
9. open up control panel and go to ports and make sure that the date rate is set to 9600
10. open minigps and set rate two 9600 with is the default rate for the unit and what com your computer assigned to the usb adapter. click connect and it should work. so at this point the gps is talking to the computer but it is not talking remotely
11. open x-ctu this is the config software for the xbee units. and close minigps since you wil be using the same channel
12. unplug the usb adapter from the computer remove the gps module and install the xbee module
read the module and change that address to something that is not zero. and change the baud to 9600. repete for other module.
13. insert xbee module in to simple board, connect gps module, connect battery
14. check leds on simple board once per sec flash tx
15. check led rx/usb board once per sec rv
16 open mini gps and it should work.
this will give you a gps telemetry module less then the size of a nine vollt battery that will run for a couple of hours offf a nine volt for about 200.00$
notes.
orientation is not a problem with the ls20033 vertical or horizontal it still maintians lock interferences from the xbee does not seem to be a problem with tracking. might be a problem with r/c autopilots however.
nine volts don't have the power to the unit i would suggest either high outputs or 3.7 volt lipos.
