Best 7 Segment Display

4Pcs MAX7219 8 Digit 7 Segment LED Tube Display Control Module for MCU/51/AVR/STM32

MAX7219 is an integrated serial input / output common-cathode display driver, which connects your microprocessor to a 7-segment digital LED display with 8 digits.This module is compatible with 5V and 3.3V microcontrollers, and you you can use it.
Material: PCB+Electronic components, LED color: Red.
Only three IO ports are used to drive the eight digit display. MAX7219 supports flicker free displays as well as cascading displays. PCV board four corners of the fixed copper stud, which can effectively precent short circuit accidents happen..
Wiring instructions (take the provided program as an example, you can pick any IO port definition can be modified in the program): VCC to 5V, GND to GND, DIN to P00, CLK to P02, CS to P01.
Digital tube is 0.36 inch 4-bit integrated cathode digital tube.
Note: VCC and GND should not be connected reversed, so as not to burn the chip.
51 MCU P0 port requires pull-up resistor, if your device does not have a pull-up resistor can be connected to other ports data lines..
A convenient four-wire serial interface can connect all common microprocessor. Each data can be addressed in the update without rewriting all displays. MAX7219 also allows the user to select each data encoding or no coding..
