Freematics ONE+ Traccar Edition is based on Freematics ONE+ pre-flashed with open-source firmware that connects to Traccar's demo server out-of-box. It integrates 4G LTE cellular module and standalone GNSS receiver and antenna as well as lots of useful peripherals for vehicle telemtry applications. For easier configuration in Traccar, the device ID is printed on the back of each unit.

DISCLAIMER: This is an Arduino/ESP-IDF compatible product working with Traccar software for prototyping/researching/hobbyist purposes. It is shipped with pre-flashed firmware expected to work out-of-box with Traccar demo server and can be configured to work with any traccar deployment. The open-source firmware working as a traccar client and its dependent Arduino libraries, though being regularly maintained and improved, are provided AS-IS without warranty of any kind. The hardware has one year limited warranty like other Freematics products.

Model A

GNSS via an external receiver containing u-blox M10 chip and antenna which can provide optimal signal reception when placed exposed to open sky. The receiver has a 1m long cable.

Model B

GNSS via built-in u-blox M10 and active ceramic antenna. Signal level varies on OBD port position and facing.

OBD-II Compatibility

Freematics ONE+ plugs into the OBD port usually located under the steering column. To check if your vehicle is OBD-II certified, open your hood and find the sticker that looks like this:

Vehicles using following vehicle protocols are supported.

• CAN 500Kbps/29bit
• CAN 250Kbps/29bit
• CAN 500Kbps/11bit
• CAN 250Kbps/11bit
• KWP2000 Fast
• KWP2000 5Kbps

Bluetooth

Freematics ONE+ has built-in dual-mode Bluetooth capability and can work with Freematics Controller App via BLE when datalogger sketch or telelogger sketch uploaded.

Cellular Module

The type of cellular module will be chosen for you based on your shipping address. If a certain type is to be specified, please leave a order comment.

SIM Card

Hologram Global IoT SIM card is supplied with the kit optionally. It needs to be activated and has a small monthly data quota free of charge. Please make sure to pop out the microSIM size (second size) and insert in the direction shown below. BYO SIM card is also an option.

MicroSD

32GB microSD card is supplied optionally. If included, the card will be inserted into the device when shipping.

Development

The most exciting thing about this product is that you can create your own unique product or solution on top of our massive accomplished work. We have been developing and maintaining a dedicated Arduino library for easy access to all hardware resources and a set of fully functional reference Arduino sketches for this product. So there is no need to start from scratch. As long as you have some basic knowledge about Arduino, you are good to go. Together with our Freematics Arduino Builder which allows configuring, compiling and uploading Arduino sketches in one simple GUI, we intend to bring the best out-of-box experience for non-professional developers. If you are a pro, we recommend PlatformIO IDE as development environment and our reference code is organized as PlatformIO projects as well, though you can still use Arduino IDE or Arduino makefile with ESP-IDF. For more information about development, please refer to the Developers Guide.
