Clock display TM1637, red

Product detailed description

The four-digit 7-segment LED display with a TM1637 driver and a central colon is a cost-effective and simple solution for displaying time, numbers, or temperature. It is controlled using only two wires (CLK and DIO), minimising the number of pins required on the microcontroller, while the driver handles multiplexing and brightness control automatically. The red digits have a height of 0.36" (approx. 9 mm). It is suitable for clocks, timers, alarm clocks, counters or simple thermometers.

Note:

• Do you need decimal points, for example for a voltmeter? Try the 8-digit 7-segment LED display with MAX7219, which features a decimal point for every digit.
• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustrative purposes only and may sometimes differ from the actual appearance of the item. However, this does not change their basic properties.
