GPS Shield - Fastrax UP501
The GPS Shield is base on the Fastrax UP501 receiver module , which with embedded GPS antenna enables high performance navigation in the most stringent applications and solid fix even in harsh GPS visibility environments. Support software(D2/D3) SerialPoart and mini SDcard interface.
It's very easy using. You just need read SerialPort and then will get the GPS data. Its also could use with Bluetooth Shield. So you can send GPS data to Android phone by Bluetooth.
The GPS Shield module interfaces to the customer’s application via one serial port, which uses CMOS voltage levels. support 3.3V / 5V IO operating. That's means 100% all Arduino mainboard compatible.

Pin definition and Rating
The GPS there are Reset button , Software SeiralPort(D2/D3), Hardware SerialPort(D0/D1), mircSD card interface(Hardware SPI)
- Rest Button for reset for UP501
- Software SeiralPort(D2/D3), that means you can use Arduino with Software SeiralPort and also Arduino monitor .
- Hardware SerialPort(D0/D1), You also could use hardware serialport to read GPS data, but can not use Arduino monitor.
- mircSD card interface, Using Haredware SPI of Arduino. D10 - SS ; D11 - MOSI ; D12 - SCK ; D13 - MISO
mircSD Card Test Programming
Includes important code snippet. Demo code like :
Test mircSD card
The projects and application examples.
Example One : Connect to PC
Step one , material preparation. Get kit from our store
There are be prepared a GPS Shield, a Arduino mainboard
Step two, connecting, DOUT-D2 DIN-D3
Step three, install Fastrax GPS WorkBench
Get the install software here and USB driver and USB-to-232 USB driver(XP, others OS check here). When driver installation starts, you will be prompted with the following dialog:
Click “Continue anyway”: If installation is successful, the Fastrax GPS Evaluation Kit port is available for use.
Step four, receiver data
To connect to your UP501 receiver, choose File -> Connect from the GPS Workbench menu. Port please select your RS232 COM, there is COM7 and Speed do not change it keep Automatic.
After your check OK button, if there show below figure 3s later, that mean your UART maybe reversed TX and RX.
The GPS Workbench loads the user interface modules, and shows them in the main window, There are GPRMC, GPGGA, GPGSA, GPGSV etc GPS data:
At last, Conclusion UP501 is activity easy to use, it can easy to get GPS data. There we do not careful analysis the GPS data, you could reference the User Guide of the Workbench or check “help” for the guide.
We also provided another free GPS software to you for more options: GPS Viewer
Example One : GPS, Bluetooth and Android Transparent Transmission
Wireless device communication with each other is in our live everywhere. Here we will show you how to transparent transmit GPS receiver module’s GPS Data to PC or Android phone or at same time by Bluetooth. That’s means we will use Bluetooth device connect GPS receiver module and send GPS Data to other side Bluetooth device, then used a USB-to-RS232 adapter transmit the data to PC. If you still do not very clear , please read on , we divided this post into three steps:
1. Material preparation;
2. Transparent transmit to Android;
3. Transparent transmit to PC. Step One: material preparation.
The project’s material include:
1. One Blueooth Shield.
2. One PC or Android phone, here we used the first and classic Android phone – G1, though it is a old guy.
3. One GPS Arduino mainboard.
Step two, transparent transmit to G1
1. Ok, if you connection is correct and then power on the GPS & Bluetooth device. The state LED will start Blink. Here we just used serial port send GPS receiver module data to Bluetooth device – Bluetooth Modem – Minimum pass-through module(HC-06), then send it to the paired device. So the next step is pair with G1.
2. How dose Bluetooth device pair with Android ? Just follow me , if you want more details please reference “Communication between Android and Arduino with Bluetooth(2)”
–> Dowload our Bluetooth App here, and then install it, and you will see a Blueooth Bee icon.
–> Click the icon enter and then click the “Open Bluetooth” enable Bluetooth to make it discoverable. There is a dialog box will appear and select “Yes”.
–> Click “Open Bluetooth” and then Click “AS Client”, it will search the remote devices and return the device address. Click the address to pair and connect it and the paire password is “1234″, if connect succeed it will return to the menu and GPS data as below:
Step three, transparent transmit to PC
1. Keep on GPS & Bluetooth connection, and connect Bluetooth Bee to PC with XBee/Bluetooth Bee USB adapter.
2. Open a serial port tool, SecureCRT or sscom32E etc, Here we used sscom32E to monitor Serial port and send AT command. Select USB adapter COM correctlly, and BaudRate is 34800, and then send ‘AT’ for testing. If return ‘OK ‘ that means you have enter AT mode. (Note: HC-05 enter AT mode must set KEY pin to High Level, If you used XBee/Blutooth Bee USB adapter you just need select the KEY switch to ‘H’ on board).
3. Before pair with each other, you should set the Bluetooth Bee to Master mode, because of pair each other must be a Master and a Slave mode. The Bluetooth Modem – Minimum pass-through module(HC-06) is Slave mode at here. The command(More details about Bluethooth visit wiki) as below:
—-> at+role = 1 //Change the role.
<—- OK // Return
—–> at+init // Initialization
—–> at+inq //Search the remote devices and return address
<—-+INQ:11:6:30074,1F00,7FFF //Slave device address
—-> at+pair=11,6,30074,20 // pair request
—–> at+link=11,6,30074 //after paired successful, link to each other
<—– GPS DATA
OK, we have transparent transmit GPS data to Android or PC side by Bluetooth, about GPS Workbench please read “Easy GPS Unit – Fastrax UP501 Receiver Module“.
