Freematics ONE+ Model B is a variant of Freematics ONE+ with integrated 4G LTE cellular module and 10Hz GNSS module + antenna, still in form of a OBD dongle that directly plugs into a car’s OBD port, and very importantly 100% software compatible with Freematics ONE+.
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.
Freematics ONE+ model B has an external I/O socket containing 2x GPIO (ESP32's GPIO35/GPIO36), VCC (controlled via GPIO15) and GND.
External analog or digital sensors can be connected with a Molex to 2.54 Dupont conversion cable (optional accessory).
Freematics ONE+ Model B integrates M8030 GNSS solution with active ceramic antenna.
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.
Freematics ONE+ has a microSD slot under the side cover. The card reader is connected to ESP32 through SPI. Standard Arduino SD library can be used for microSD card access.
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.
We provide firmware customization and technical support for application integration. White label or custom label enclosure can be supplied for this product with a MOQ.
