Introduction
The OpenTracker v2 is the first 100% Arduino compatible, fully open source, commercial grade
GPS/GLONASS vehicle tracker development board that comes with a free web interface for tracking.
The OpenTracker v2 hardware includes the same powerful 32-bit ARM controller as the Arduino DUE, a
GSM/GPRS modem for wireless connectivity, a GPS/GLONASS module with Assisted-GPS, CAN-BUS,
plenty of I/O, and a wide operating temperature range of -35°C to +80°C.
The hardware is pre-programmed and able to send tracking data right out of the box; you will only need the
SIM card and to register the device on our on-line tracking software.
After the configuration is complete, you will see your device on the map.

Hardware Description
Board Overview
OpenTracker is an open-source development platform for vehicle tracking applications, compatible with
Arduino software and development environment.
The OpenTracker hardware includes a powerful 32-bit controller (as found on the Arduino DUE), a quad-
band GSM/GPRS modem with micro-SIM card socket, GPS/GLONASS module, CAN interface, 2 analog
inputs, 2 relay driving outputs, an internal expansion interface (including SPI, I2C, UART, GPIO, ADC and
modem audio) and a micro-USB interface to develop additional features.
Design files, firmware and Arduino board support packages can be found on GitHub:
https://github.com/geolink/opentracker-hardware
https://github.com/geolink/opentracker
https://github.com/geolink/opentracker-arduino-board
Processor
The Atmel SAM3A4C microcontroller is a 84MHz 32-bit ARM Cortex-M3 core with 256KB embedded Flash
(2 x 128 KB) and 64 KB embedded SRAM.

Quick Start Guide
Install Arduino IDE
The Arduino IDE is an integrated development environment used for OpenTracker.
If you plan to modify the program code or write your own there is no way around it.
Please note:
The tracker comes pre-programmed, if you only want to get started tracking just skip this step.
OpenTracker requires Arduino IDE 1.6.7 or later. The download should be just below 100MB while
downloading the installer and the installation process you may move on the next steps.
Please download the latest version here:
http://arduino.cc/en/Main/Software
Insert SIM Card
OpenTracker has got one Micro SIM slot. Larger SIM cards can be cut into micro SIM in any Store that sells
SIM Cards or Mobile phones.
1. Unlock slot 2. Open cover 3. Insert SIM 4. Close slot and lock it
For your convenience the SIM PIN should be deactivated.
If this is not an option, the SIM PIN has to be entered into the “tracker.h” and flashed into the
Tracker.
Connect Antennas
Take the antenna cable ends, plug them one after another into the antenna connector on the OpenTracker.
Turn the antenna cable connector clockwise. Ensure to connect the antennas tightly.
Make sure to plug the GPS/GLONASS antenna (here shown orange) into the connector labeled GPS on the
board and the GSM antenna (here shown in blue) into the connector labeled GSM.

Connect USB Cable
Use a micro USB Type B cable and plug it into the board as shown in the picture below.
This is an optional step. Only necessary if new software has to be installed or developed.
Connect MOLEX Cable
Ensure the Latch on the connector is faced up as shown in the picture below.
Push the connector until it clicks.

User Manual (1.4.0) OpenTracker 2.4 9
Connect Power source
OpenTracker supports 12V/24V nominal power supplies (the full range is 8 –32 Volts DC).
Please connect first the battery negative (B–) terminal to pin 6 (black wire), then the positive (B+) terminal to
pin 1 (red wire) through a 2A fuse, as in the picture below. Then connect vehicle ignition (IGN) to pin 10
(white wire), or connect pin 10 to pin 1 if ignition output is not available
Start up the tracker
Please ensure to insert the correct data, as the wrong information may cause higher costs on your SIM bills
or be a source of connection problems.
Setup APN
Send SMS message to the inserted SIM card number to configure APN for your GSM provider (WAP APN
are not supported):
#pass,apn=APN_NAME
Example:
#pass,apn=internet
The module will reply with the following response:
APN saved
Send 2 SMS messages to the inserted SIM card number to configure APN username and password
(optional for some GSM providers –default username and password are empty):
#pass,gprsuser=APN_USERNAME
#pass,gprspass=APN_PASSWORD
Example:
#pass,gprsuser=guest
#pass,gprspass=guest
The module will reply with the following response:
APN username saved
APN password saved

Change SMS password
Optionally, change SMS password by sending following SMS command:
#pass,smspass=NEW_PASSWORD
Example:
#pass,smspass=mynewpass
After changing the SMS password, the SMS commands should begin with your new password, like:
#mynewpass,COMMAND=ARGUMENTS
Please note, depending on the current status of the device, it may take a while until the SMS
response is sent.
SMS Commands
Summary of the SMS commands for the initial configuration. The unit will accept only one command at a
time and send a reply on successful command execution (this may take a while).

Register
To use the Geolink web interface (www.geolink.io) you need to register your OpenTracker device.
Please follow this guide: https://geolink.io/guide.php
Make sure your device is configured, powered and ignition is on, so that it connects to the
tracking server.
