When driving, the driver needs to be as attentive as possible. And in order not to waste time on taking readings from the dashboard, the proposed "on-board computer" has a large color TFT display, which displays information about speed, kilometers driven, coolant temperature and other operational information. The device is installed on the dashboard in a convenient place for the driver, in case of violation of important indicators of the car, an audible signal is emitted. Most importantly, you can set the speed limit, and when it is exceeded will sound an audible alarm. This is convenient, especially on the highway, when the speed is no longer felt. Please note: for connection, the car must have an OBDII connector.
