This is device for read data in real time from the OBD-II port through the K-line pin using ISO 9141-2. The device is connected with three wires: + 12V power supply, ground, K-line port. The device is plugged directly into the OBD-II diagnostic connector. An ELM interface is not required or needed. The L9637 is a monolithic integrated circuit containing standard ISO 9141 compatible interface functions. Arduino Nano based on the ATmega328 processor provides support for sent and received messages from K-line, and displays the received data on the OLED display using the I2C protocol. The received data is displayed on the SH1106 OLED display. To simplify the system, Arduino Nano power is supplied via the miniUSB port from the power bank. Of course, you can use an additional 7805 chip and power the entire system from the vehicle installation.
