The recommended operating temperature range for the DD-12HWB is -20°C to 70°C, with a storage temperature range of -30°C to 80°C.
The DD-12HWB can be interfaced with a microcontroller using a serial interface, such as SPI or I2C. The display requires a 5V power supply and can be controlled using a 3.3V or 5V logic level.
The typical current consumption of the DD-12HWB is around 20mA to 30mA, depending on the brightness setting and the number of segments turned on.
The DD-12HWB is suitable for indoor use only. If you need to use it in an outdoor application, you may need to add additional protection, such as a UV filter or a protective coating, to ensure the display remains readable in bright sunlight.
The brightness of the DD-12HWB can be adjusted by changing the current limiting resistor value or by using a PWM signal to control the display's enable pin.
