Polaris is a Python programmable open IoT platform, designed for remote logging and Cloud applications. It is an excellent GPS/GLONASS vehicle tracker, available with 2G, 3G, LTE, NB-IOT modem. The Polaris application, available in Python Zerynth or Arduino, is open source so that it can be easily changed and customized.

if you want to see a comparison between Polaris and OpenTracker V2, have a look to this article.

Polaris can function as a GPS/GLONASS vehicle tracker, available with 2G, 3G, LTE, NB-IOT modem, but it’s so much more, too. It is a Python programmable open IoT platform, ready to connect to the Cloud with just a few lines of code. Polaris is also 100% Arduino compatible.

Polaris is the evolution of the OpenTracker, the most popular open-source vehicle tracker board in the world, which we developed in 2014.

Python programmable

With IoT in mind, we couldn’t think of a better programming language than Python. That is why Polaris is Zerynth-powered and Python programmable.

Thanks to the Zerynth (*) license onboard you can program it in Python right out of the box. Zerynth also allows C/Python hybrid programming.

The full Python application is released open source. Here are the Zerynth Studio download links for Windows, macOS, Linux (compatible with r2.4.0 – r2.5.0). Zerynth v2 documentation, API and demos is available here.

(*) Zerynth has a really small footprint. It requires just 60k-80kB of Flash and 3-5kB of RAM. Zerynth also integrates the RTOS of your choice with multithreading support. When it comes to security, it offers support for HTTPS, SSL/TLS, secure hardware encryption, and Blockchain.

Arduino compatible

As we said Polaris is 100% Arduino compatible. It is natively supported by the Arduino IDE, taking advantage of the vast Arduino code base.

The full Arduino application is released open source on the GitHub channel.

Advanced Features

Polaris also allows you to add a Li-Po battery, and run it without the car battery. For example, it can be added to a bicycle, thanks to that external power source.

With several analog inputs it can be connected to various sensors or collect data from the CAN bus. Several digital outputs are also available to directly control relays or other external loads. The sensor data can then be easily sent to the Cloud for remote monitoring. This makes Polaris ideal for industrial machinery where it is required to measure things like oil pressure, crane positioning, and so on.

When it comes to expandability, Polaris is quite versatile. There’s plenty of digital and analog I/O, communication interfaces like SPI, I2C and UART, and a MikroBUSTM slot which allows you to take advantage of more than 600 Click boards. This means you can add all sort of functionalities to Polaris: from OLED displays, buttons and UV sensors to motor control and motion sensors.

Stand-alone or in a kit

Polaris it is available as a stand-alone product and in a kit. The board comes in three versions: 2G, 3G, and NB-IOT.
Of course, the kit includes everything that you need to install Polaris right out of the box. You can choose between two kit options: with a Li-Po battery, or without it.

The kit includes:

  • Polaris
  • a metal case
  • an antenna
  • accessories

It is ready to be used as a vehicle tracker. Because its wide voltage input, it can be used on motorcycles, cars, trucks, heavy machinery, etc. Polaris offers several low power modes (down to <50uA), perfectly suited for IoT and industry 4.0 devices and applications.
