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+.

Features

  • Dual-core Arduino programmable SoC
  • High performance Wi-Fi and Bluetooth communications
  • G-force measurement and motion/orientation detection
  • High update rate GPS/GLONASS geolocation
  • Access to all standard OBD-II PIDs, DTC, VIN from vehicle ECU
  • CAN bus data sniffing
  • Car battery voltage reading
  • Data storage in internal Flash or microSD card (up to 64GB)
  • Real-time data transmission over WiFi and 4G cellular network (LTE CAT4)

  • Integrated SIM7600A-H or SIM7600E-H 4G LTE CAT4 cellular module
  • Integrated buzzer (PWM or DAC driven)
  • Enclosure dimensions: 60x48x20mm
  • Typical power rating @80Mhz: 20mA (WIFI inactive) / 50mA (WIFI active) / 150mA (LTE active)

Physical Interfaces

  • OBD-II male connector
  • microUSB port
  • microSD card slot
  • SIM card slot
  • GPIO socket (Molex)

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

External I/O

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).

 

GNSS

Freematics ONE+ Model B integrates M8030 10Hz GNSS solution with active ceramic antenna.

 

 

Cellular Module

Freematics ONE+ Model B integrates SIM7600A-H or SIM7600E-H 4G LTE CAT4 module.

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

 

SIM Card

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.

 

MicroSD

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.

 

Low-Power Mode

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.

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.

 

 

Branding & Customization

 

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.
