Freematics OBD-II Emulator MK2

SKU: TEL0099

Freematics OBD-II Emulator MK2 (world’s smallest) simulates OBD-II protocols (KWP2000, ISO9141, CAN). It has a 16-pin OBD-II port, responding to PIDs, up to 6 DTCs, and VIN requests (VIN alterable). Controlled via USB GUI or BLE iOS app (BLE version), it supports TTL for Arduino/sensor integration. Ideal for OBD-II dev and adding OBD-II to non-equipped vehicles.

    The emulator has following interfaces on its enclosure:

    • 16-pin female OBD-II port
    • DC 12V input
    • USB port
    • 6-pin XH-2.54 socket (Tx/Rx/GND/3.3V/5V/12V)

    NOTE: The 6-pin XH-2.54 socket provides an interface for serial TTL connection as well as DC power supply of 3 different voltages. A micro-controller board or Arduino can be connected with the emulator and act as the host controller. The source of data may come from rotary switches or real sensors attached to them.
