Freematics OBD-II Emulator MK2
The Freematics OBD-II Emulator MK2 is the world's smallest OBD-II emulator, providing a standard 16-pin female OBD-II port that responds to diagnostic requests just like a real vehicle. It simulates CAN bus, KWP2000, and ISO9141-2 protocols, making it an invaluable desk-side tool for developing and testing OBD-II applications without needing access to a car.
The emulator responds to all standard OBD-II PIDs, supports up to 6 active diagnostic trouble codes (DTCs), and provides configurable VIN responses. Control it via USB with the GUI software, or wirelessly from an iOS device via built-in BLE. A TTL serial connector allows integration with Arduino or other microcontrollers as an external data source.
