Freematics OBD-II UART Adapter V2.1 coming soon

Freematics OBD-II UART Adapter V2 has been upgraded. The new V2.1 is completely compatible with V2 and has several enhancements including:

  • 9-DOF motion sensor (instead of 6-DOF)
  • Built-in 9-DOF quanterion algorithm for orientation detection
  • New AT commands for reading calculated pitch, yaw, roll values
  • Unpluggable serial cable (easier for using as a USB adapter)

The new version will start to ship in no more than 2 weeks time from now. Meanwhile, the V2 is out of stock but you can still place order for them and we will ship V2.1 instead when the stock come.

UPDATE: Ready for order now!

Free telematics server software for everyone

Freematics Hub is a free telematics server software that is based on the design of Freematics Hub and is perfect for use with Freematics ONE+ (and literally any programmable telematics devices). It runs on any computer and turns it into a telematics data center that receives and stores data from remote telematics devices through cellular network, WIFI or even USB. Live data and geographic locations are stored as local files and instantly displayed on a concept user interface. More importantly, the software running as a server provides a set of REST APIs for access live and history data for further development.

We will release the software together with Freematics ONE+ shortly.

UPDATE (July 3rd): Beta version now available for downloading!

Freematics ONE now comes with 3G xBee module

We have been working on a new 3G WCDMA/GSM xBee module for Freematics ONE vehicle data logger. It’s based on SIMCOM SIM5360E.  Comparing to former SIM800L based GSM/GPRS xBee module, the new comer will provide a faster data link and more importantly continue to work in regions where 2G network is about to be shut down (like Australia).

Today we are happy to announce the release of the new module as a new option for Freematics ONE, which can be ordered and shipped with Freematics ONE right away. Head to our online store to place your order now.

Freematics ONE now comes with MPU-9250

Freematics ONE now comes with MPU-9250 MEMS sensor! The supporting Arduino library and example sketches (in Github) have been updated for 9-axis MEMS data access. To order Freematics ONE with MPU-9250, make sure to choose MPU-9250 in MEMS option on the order page.

Code clip of accessing MEMS data.

int acc[3]; // accelerometer data
int gyr[3]; // gyroscope data
int mag[3]; // magnetometer data
int temp; // device temperature (in 0.1 celcius degree)
if (memsRead(acc, gyr, mag, &temp)) {
  // success
