LED 7Segment 4-fach mit Schieberegister 74HC595

vierfach 7 Segment LED Anzeige rot Ansteuerung über Schieberegister  74HC595 (dadurch nur drei Datenleitungen nötig) kaskadierbar

Abmessungen Board ca. 63.6x25.2mm

Description:
1.2-way bright red digital display module, there are four screw holes. Easy to install.
2.Use two 74HC595 SMD drives, digital tube were each band limiting resistor, to ensure uniform brightness.
3.Static drive, in the digital unchanged, SCM has not refreshed. Non-dynamic scanning, saving MCU system resources.
4.Simple interface, VCC +, GND -, SDI data, Shift clock SCLK, latch LOAD, only three wire interface with the microcontroller, saving microcontroller IO
5.Data output for easy cascade.
