With dynamic simulation, real-time LCD display of the main parameters of the function, very convenient and practical   provides more than 150 real-time simulation data, close to the real car environment, can let you save fuel and car supports frame number modification and saving, as well as simulation of three fault codes provides 220V to 12V power adapter, so that the simulated environment can more realistically approximate the real car environment   More than 7 configuration specifications at your choice Main features: board carries LQFP48 STM32F103CBT6 chip (Flash:128KB,RAM:20KB), rich interface, powerful function, fast running speed board carries the standard 16pin OBD connector   board with 320*240 LCD screen display, convenient for real-time data display board is equipped with a 7-bit dial-code switch to facilitate switching between various protocols board is equipped with 3 LED indicator lights and 1 self-locking switch input to facilitate the simulation and prompt of various fault codes board contains the output of the buzzer for convenient prompt sound board contains three user-defined keys - left and right keys for page turning - and the middle keys are temporarily disabled for future ignition/flame-out simulations OBD emulators support the following seven protocols... 1 ISO14230 addr - 4 K 2 ISO14230-4 K hl 3 ISO9141 addr - 2 K 4 CAN ISO15765 - STD - 500 k 5 ISO15765-4 ext - 500 k CAN 6 CAN ISO15765 - STD - 250 k 7 ISO15765-4 ext - 250 k CAN   Our OBD simulator is a passive unit that simulates OBD data in a car. It needs to issue a command before it returns all kinds of parameter data. If you want to buy data that is used to simulate your car, you should first understand the OBD protocol format of your car before you decide   If the OBD protocol of your car happens to be supported by our OBD simulator, you can buy it. If you buy it, you can simulate it and you can use it. Please keep this in mind 4. Hardware resources of on-board OBD simulator 1OBD simulator 1 12V power adapter   5.
