The instrument panel is the interactive interface between humans and electric bicycles. It displays operating parameters, battery level, driving distance, and other information for the driver. It is an important component of a car. Mainstream electric bicycle instruments use LCD or LED screens.

There are DC-DC modules, microcontroller modules MCU, and display modules. In order to accurately test the battery voltage, the module needs to directly obtain power from the battery. Therefore, the instrument requires a high-voltage DC-DC module to change the power supply to other internal modules: the MCU reads speed information from the controller and displays it on the display screen after internal processing.

The speed and mileage information are displayed on the display screen: At the same time, in order to ensure that the information on the display screen can be clearly seen under various lighting conditions, the display screen needs to adjust the backlight driving current at any time and adjust the brightness of the display screen as needed. Required. The voltage required for the display screens in MCU and instruments is usually 5.0V, so the high-voltage DC-DC module can directly output 5.0V to meet power supply requirements.
