MAX7219 8 Digital Segment Digital LED Display Tube module For Arduino U8I6

Description

MAX7219 8 Digital Segment Digital LED Display Tube module For Arduino U8I6
MAX7219 is an integrated serial input / output common-cathode display drivers, which connects the microprocessor and 8 digit 7-segment digital LED display.
you can also connect a bar graph display or 64 separate LED.
Includes an on-chip type B BCD encoders, multi-channel scanning loop, segment word driver, but also a 8x8 static RAM that stores each data.
Only one external register is used to set the current of each LED segment.
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.
The entire device includes a 150μA low-power shutdown mode, analog and digital brightness control, a scan-limit register allows the user to display 1-8 bit data, there is an all LED light detection mode.
Only need three IO ports can drive eight digital tube!
PCV board four corners of the fixed copper stud, which can effectively precent short circuit accidents happen
0.36 inch and four digital tube one common cathode LED
The module compatible of 5v/3.3v microcontroller(51/AVR/STM32...)
Wi instructions (a program, for example, you can pick any IO port definition can be modified in the program):VCC→5V
GND→GND
DIN →P00
CS →P01
CLK→P02
e:VCC and GND do reversed, it would burn the chip
51 MCU P0 port requires pull-up resistor, if your device does have a pull-up resistor can be connected to other ports data lines
size:8.2*1.5CM/3.35*0.59 inch
mateiral:CCL
colour:BLUE
packing:1*LED Display Tube module
e: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
