Freematics ONE+ Traccar Edition is based on Freematics ONE+ Model B and comes with Hologram Global IoT SIM card and pre-flashed 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 a Arduino/ESP-IDF compatible development kit working with Traccar software for prototyping/researching/hobbyist purposes. Although it is expected to work out-of-box, the firmware source code and Arduino libraries are provided AS-IS and without warranty of any kind. If you decide to use it in any commercial applications, you are required to test and improve the firmware source code or develop your own from scratch. The hardware has one year limited warranty.
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.
M8030 10Hz GNSS solution with active ceramic antenna is integrated and managed by co-processor which also decodes the NMEA stream and make the decoded information ready for ESP32 to fetch.
Freematics ONE+ Model B integrates SIM7600A-H or SIM7600E-H 4G LTE CAT4 module.
|Mobile Network Bands||LTE-TDD B38/B40/B41
|ransfer Speed||LTE CAT4: Uplink up to 50Mbps, Downlink up to 150Mbps
HSPA+: Uplink up to 5.76Mbps, Downlink up to 42 Mbps
UMTS: Uplink/Downlink up to 384Kbps
EDGE: Uplink/Downlink up to 236.8Kbps
GPRS: Uplink/Downlink up to 85.6Kbps
A microSIM card is needed for using cellular network and is inserted as shown below.
Global SIM cards like Hologram IoT SIM card are supported.
Freematics ONE+ has a microSD slot under the side cover which is connected to ESP32 via SPI. Standard Arduino SD library can be used for microSD card access.
The internal buzzer is connected to ESP32’s GPIO25 and can be driven by PWM or DAC.
Freematics ONE+ enters and leaves low power mode programmatically. In low power mode with all peripherals (GPS, GSM, WIFI) powered off, the power consumption is around 10mA. This prevents car battery from going flat while the main controller is still able to run code and perform low-power tasks like motion detection by MEMS sensor.

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.
