Freematics was on the stage of Maker Faire for the 4th time. The weekend spent in Powerhouse Museum for Sydney Mini Maker Faire was just as exciting as the previous ones we went for. One slight difference was that some visitors had already heard about us online and some even had purchased our products before. It was good to be face-to-face with users, whether past or potential, and we got lots of good feedback.
Tomorrow Freematics will be present at Sydney Mini Maker Faire. Here is the slideshow about what we are going to tell people.
After having taken part in the Maker Faire Bay Area in May, we are heading for PowerHouse Museum in Ultimo, Sydney. Two weeks later we will present our 4th Maker Faire exhibition worldwide and the 2nd one in Sydney. The event website has already posted a brief introduction. In the coming exhibition, we will focus on our just upgraded Arduino OBD-II data logger kit #3 and the new generation of OBD-II emulator and demonstrate both of them on site. Come to see the products and us if you are around!
After 3 month’s development and testing, Freematics OBD-II Emulator MK2 is now ready for order!
Freematics OBD-II Emulator MK2 is world’s smallest OBD-II emulator with KWP2000, ISO9141 and CAN bus simulation. It provides a 16-pin female OBD-II port which is identical to that of a real car and responds to requests for standard OBD-II PIDs from plugged-in OBD-II compliant device. It emulates up to 6 active vehicle diagnostic trouble code (DTC) as if a real car has when encountering a component malfunction or fault. Request for VIN is also responded and the VIN can be altered.
The emulator connects to PC via USB cable and is operated via an easy-to-use software GUI. Secondary development is possible with serial TTL connector available for connection of interaction with Arduino or other embedded system with source of data (e.g. sensors).
Freematics OBD-II Emulator is practically useful and cost effective for OBD-II related application development on desk. Once extended with external data source, it can even be used to provide an OBD-II port for vehicles that don’t have a real one and thus existing OBD-II device/software can also work with the vehicle.

Tomorrow we will be part of the world’s biggest event for makers, the Maker Faire Bay Area! Last year in NYC, we came to the stage of Maker Faire for the first time and was deeply impressed and motivated by the event. In the following 8 months, we have done a lot towards the goal of our project. We went onto Kickstarter and got hundreds of backers after the campaign. We set up our online store for accepting orders from worldwide.We kept improving our key product, Freematics OBD-II Adapter and released V2 of it. Being in the maker movement, we are just motivated to go towards our goal while also being able to enjoy the the whole process.
We are so excited to come back to Maker Faire to show the world what we have done through the months. In this show, we will be presenting 3 major works.
This is the core product of the project. The V2 comes which has following changes/improvements:
Freematics OBD-II Emulator V2
Our OBD-II emulator is really a derivative product which was originally made for our internal use only. When we tried pushing it to market, it got unexpected popularity so that we decided to make it better. The original version uses 9 knobs for adjusting the value of 9 OBD-II PIDs. The physical knobs are handy to use but in some cases when we want to adjust more PIDs or do it programmatically, a data interface is necessary. The V2 comes with a serial data interface of a simple AT command-set which goes through TTL, USB or Bluetooth. By sending AT command, the value of OBD-II PIDs can be altered and the change is reflected on the simulated data bus and finally on the OBD-II port. The physical knobs are removed as we will make a good PC software and iPad/iPhone App for the same and even better experience. As the emulator also provides TTL serial UART breakout, it is possible to control the emulator with an Arduino or other hardware. This can be used to emulate a standard OBD-II port on a vehicle which does not have one with actual data obtained by other means.
Arduino OBD-II Logger Kit based on Arduino DUE
We have been providing different Arduino OBD-II Logger Kits which are popular among makers who want to make a vehicle data logger with a display. The Kit #3 originally consist of an Arduino MEGA 2560 and a 2.8″ TFT LCD shield. It is to be upgraded to Arduino DUE and 3.2″ TFT LCD shield.
The above 3 highlights are what we will present at this Maker Faire. Come to see us if you are hanging around!
Freematics is going to Maker Faire Bay Area (May 17 & 18). We will exhibit the latest version of Freematics OBD-II Adapter and some other open-source hardware products and kits of ours. Last year’s World Maker Faire in New York is our very first chance to expose to the spotlight of world-class maker event. 7 months has passed since then. We have performed our very first Kickstarter campaign and have never stopped pushing the project forward.
If you happen to be hanging around Bay Area in May and would like to talk about anything about the project or our products, come to our table in the San Mateo Event Center! Our project number is 20340.

After our first Kickstarter campaign was over, we have been keeping up pushing the project Freematics forward, though the goal of the campaign wasn’t reached. The sample of Freematics OBD-II Adapter V2 is now under testing. The V2 has several changes and improvements. The most important one is the GPS support. One serial UART of STM32 was led out to 4 pins for connecting GPS module. The STM32 processor will process the NMEA data input from the connected GPS module and parse it. We have extended ELM327 AT command-set to provide access to the parsed data. The added commands are:
