Using the LinkSprite GPS Shield (w/ SD Slot) for Arduino

Help & Support Robot Parts

I purchased a couple of LinkSprite GPS Shield (w/ SD Slot) for Arduino, part number RB-Lin-58 at link robotshop.com/en/linksprite-gps-shield-sd-slot-arduino.html?___SID=U

The manufacturer’s software links led to some bad software which the techs at RobotShop quickly removed and provided the SIRFdemo, which is currently on the link page.

I have downloaded the tinyGPS software, which I cannot get to work.

I found someone with a similar problem at linksprite.com/forum/index.php?topic=295.0

I followed their instructions, except for using XCTU, and cannot get the GPS to work.

I downloaded the latest XCTU, but it looks for a radio and cannot find one. XCTU finds the arduino but no luck on the GPS.

I have tried both GPS units I purchased.

Can someone point me or step me through the right direction to get data out of this unit?

Ultimately, I would like to setup an Arduino with the GPS Shield and and XBEE shield. I would like to have two of these who can communicate GPS information to each other.

Plan B is to setup an Arduino with the GPS Shield to record data to the SD card which I can read.

Good Morning Jeffrey,

Thanks for the help. I did redefine the pins in tinyGPS, but set them to something other than defined in your post. I will try the new definitions today.

Have you changed the tinyGPS example to use pins 3 and 4 for RX and TX?

#define RXPIN 3
#define TXPIN 4

You can’t use the information on the LinkSprite forum (the link you provided) because it is for a different product that uses pins 0 and 1. The reason they have to remove the ATmega chip, or upload a blank Arduino sketch, is because they want to use the USB-to-UART (TTL) circuits to allow their computer to communicate directly with the GPS module and don’t want the ATmega chip to interfere.

The GPS shield that you have doesn’t have the same problem because it uses different pins.
