Freematics ONE+ is our most powerful Arduino programmable vehicle telematics prototyping platform, an enhanced version of Freematics ONE with forward compatibility.

Freematics ONE+ is in form of a OBD dongle which plugs directly into a car’s OBD port and works as a standalone computing device which has access to vehicle's ECU, high accuracy GPS, motion sensor and possibly some external sensors. Collected data can be processed in real-time, stored in internal Flash or microSD card and transmitted via BLE, WIFI or cellular network.

Features

  • Dual-core ARM SoC processor programmable as Arduino
  • High performance WIFI and BLE communications
  • G-force measurement and motion/orientation detection
  • High update rate GPS positioning
  • Access to all standard OBD-II PIDs, DTC, VIN from vehicle ECU
  • Car battery voltage reading
  • Data storage in internal Flash or microSD card (up to 32GB)
  • Exchanging data with other devices by USB or BLE
  • Transmitting data remotely over WIFI or cellular network
  • Programmable as Arduino with dedicated Arduino library

  • SIM800L or SIM5360 bee modules for cellular network connectivity
  • Enclosure dimensions: 60x48x20mm
  • Typical power rating @80Mhz: 20mA (WIFI inactive) / 50mA (WIFI active) / 180mA (3G active)

 

Physical Interfaces

  • OBD-II male connector
  • microUSB port

  • SIM card slot (when cellular module is present)
  • GPIO socket (Molex)
  • xBee socket (onboard)

 

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+ has an external I/O socket on its enclosure. The 4-pin socket contains of 2x GPIO (from ESP32), VCC and GND.  A 2.54 Molex connector is used for wiring. The line definition of the connector is as following.

  1. GND
  2. GPIO32 / Rx2 (ESP32)
  3. VCC (5V)
  4. GPIO33 / Tx2 (ESP32)

GPSConnector

GPS

Freematics ONE+ supports high-accuracy geolocation positioning with an external GPS receiver connected to the 4-pin GPIO connector. The optional M8030 10Hz GPS receiver provides high accuracy (up to 2 meters) and high update rate (10Hz). The receiver has a 1.5m long cable and can be conveniently located where exposed to open sky.

 

Cellular Network Module

Freematics ONE+ has an xBee socket inside to provide the possibility of extending wireless communication capability with various bee modules. We have designed and provide 3 types of cellular network modules working perfectly with Freematics ONE+. Please be noted that xBee socket uses 5V VCC instead of normal 3.3V due to the efficiency consideration for powering cellular modules. Following chart compares the 3 types of cellular modules currently available.

When cellular network module included, Freematics ONE+ comes with built-in antenna inside enclosure. It works great in most cases. To improve cellular network signal level in areas with poor coverage, there is an option of external antenna connected via a SMA connector which can boost signal by 4-8dB and significantly reduce the heat generated by the working network module. Please be noted the antenna option is not available from quick order.

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.

Schematic

The schematic is here. We supply head-less (no OBD-II header) or bear PCB versions. Please contact for details.

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.
