GPS Micro-Mini
sku: GPS-08936
Description: This is a tiny GPS module that uses the MN5010HS module in conjunction with a GPS chip antenna. Built in LNA makes for reliable locks from satellites. Selectable baud rate and NMEA and SiRF outputs from a jumper on the back of the board. Comes with all relavent pins broken out, including a VCC, RX, TX, and GND header for an easy plug in connection to our FTDI USB to Serial board.The MN5010HS has the same size and similar footprint to the MN1010. The MN5010HS has improved sensitivity, an integrated LNA, built-in RTC, and integrated single power supply making it very simple to use.
Note: To send a NMEA command to the module, you need to send a /r/n or hit Ctrl-Enter to send the command from a terminal program.

If you would like to tell us more, you can fill out our form if you need some psycho-suggestive questions. Go to the form.
i using arduino bluetooth, but i can't see in serial monitor.
how can i use? pls
I've connected this module with your BB FT232RL USB>Serial, i had no problem in receiving data from it ... but I can't get any fix !!!
I tried to read configuration options (datum, ...) but it seems that it cannot receive any serial input ... I'm even trying to stop navigation typing this command through hyperterminal
$PUNV,STOP*29^CtrlEnter
but nothing happens ... where I'm wrong ?
Thanks.
I would appreciate if someone could help...
We test all of our GPS boards for locks. The microMini GPS will get a lock in less than a minute outside here at Spark Fun. If you are having issues, the best idea would be for you to return the device back to us for testing. If you still are having issues, there could be environmental factors that are causing interference.
Things to keep in mind if you are having trouble; regulate your power supply (preferably to 3.3V in the microMini's case), minimize interference from other electronics, try not to test the unit in you hand (the impedance will be raised and this will de-tune the antenna network), and be sure to test the unit outside.
I am also having problem to get lock. My GPS micro-mini module is connected to Sparkfun's serial-USB FTDI board. Could the 3.3V power supply be the issue here? Would 5V supply help? Did you make any experience here? Thanks.
I have similar problems with this GPS. Walking outdoors for about 30 minutes (twice !) gave no position fix. Serial data runs ok. A EM-406 receiver that was run also during that test gave normal fix in about 5 minutes.
What's wrong with Micro-Mini GPS?

I recently bought the GPS Micro-Mini based on the MN5010HS GPS.
On the description of the product, you specify that there are selectable baud rate and NMEA and SiRF outputs from a jumper on the back of the board. On my product, I don't have any jumper!!!
Moreover the spacing between OPT1, OPT2, GND and VCC does not allow to connect jumpers.
You have left OPT1 and OPT2 floating which does not allow to configure the baud rate, as explained in the MN5010HS Design Guidelines.
What are the reasons why you left OPT1 and OPT2 floating, and how come didn't you separate them with 0.1" standard pin headers?
Thanks
Otherwise, these chip antennas amazingly well -- even for getting first lock indoors. This module seems to consume very little power, out performs some of our past ceramic antenna designs, and is quite a hit with us.
