74HC595 unidad estática 2 módulo de pantalla de tubo digital se puede conectar en serie 0,5 pulgadas 2 bits 3 bits 4 bits rojo de alto brillo

1. 2-way high brightness red digital tube display module has 4 positioning screw holes for easy installation.

2. Using 2 chip 74HG595 driver, digital tube each segment with resistor current limiting to ensure uniform brightness.

3. static drive, in the case of digital unchanged, the microcontroller does not have to keep refreshing, non-dynamic scanning, saving microcontroller system resources.

4. Simple interface VCC positive, GND negative, SDI data, shift clock SCLK, latch LOAD, only 3 wires and microcontroller interface, save microcontroller 10

5, there are data output, convenient cascade, for example, 4 digital tube module (regardless of how many) can be one with a, the most front of a table header of the 3 wires connected to the microcontroller can be.
