Product description

The 1.2-channel bright red digital tube display module has 4 positioning screw holes for easy installation.

2. Use 2 SMD 74HC595 drivers, each segment of the digital tube is equipped with resistor current limiting to ensure uniform brightness.

3. Static drive, under the condition that the number remains unchanged, the single-chip microcomputer does not need to be refreshed all the time, non-dynamic scanning, saving the system resources of the single-chip microcomputer.

4. The interface is simple: vCC positive pole, GND negative pole, SDI data, shift clock SCLK, latch LOAD, only 3 lines are needed to interface with the microcontroller, saving l0 of the microcontroller

5. There is data output, which is convenient for cascading. For example, 4 digital tube modules (regardless of how many) can be connected one by one, and the 3 wires of the first meter can be connected to the single-chip microcomputer.
