MAX7219 8 Bit 7-Segment Digital Tube Red Display Control Module for Arduino

Features:

• 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.
• A convenient four-wire serial interface can connect all common microprocessor. Each data can be addressed in the update without rewriting all displays.
• The entire device includes a 150 uA 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, the module compatible of 5v/3.3v microcontroller.
• PCV board four corners of the fixed copper stud, which can effectively prevent short circuit accidents happen.
• 10MHz Serial Interface
• Individual LED Segment Control
• Decode/No-Decode Digit Selection
• 150 uA Low-Power Shutdown (Data Retained)
• Digital and Analog Brightness Control
• Display Blanked on Power-Up
• Drive Common-Cathode LED Display
• 24-Pin DIP and SO Packages
• Wiring 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
• Note: VCC and GND can not be reversed, otherwise it would burn the chip.

Package Includes:

• 1 x MAX7219 8 Bit 7-Segment Digital Tube Red Display Control Module for Arduino
