Freematics OBD-II Emulator MK2 is world’s smallest OBD-II emulator with KWP2000, ISO9141 and CAN bus simulation. It provides an 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.

Turn off consumers.OBD-1. 11.OBD-1 Serial Interface.Toyota. Easy tuning, great drivability and cheap. Now all we need is someone to figure out how to easily mod the stock ecu rev limit. Serial communication on pins TX/RX uses TTL logic levels (5V or 3.3V depending on the board). Don't connect these pins directly to an RS232 serial port; they operate at +/- 12V and can damage your Arduino board. Serial is used for communication between the Arduino board and a computer or other devices. Wiring the MCP2515 Shield with OBD on Arduino In this illustration we will going to wire the CAN BUS (Controller Area Network Bus) Shield with Arduino, if you don’t have any background how CAN (Controller Area Network Bus) works please refer this this link.

The emulator is controlled by GUI software via USB interface. The BLE enabled version provides additional wireless control by iOS device (iPad/iPhone) with our Freematics Emulator App.
