This is a 74HC595 3 digit 0.5inch seven segment display module, a very versatile seven segment display module that can work on several microcontroller project, with the following feature:
1.2-way bright red digital display module, there are four screw holes Easy to install.
2.Use three 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 serial 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.
- VCC +
- GND –
- SDI data
- Shift clock SCLK
- Latch LOD
