Only one\nexternal register is used to set the current of each LED segment. A convenient\nfour-wire serial interface can connect all common microprocessor. Each data\ncan be addressed in the update without rewriting all displays. MAX7219 also\nallows the user to select each data encoding or no coding. The entire device\nincludes a 150μA low-power shutdown mode, analog and digital brightness\ncontrol, a scan-limit register allows the user to display 1-8 bit data, there\nis an all LED light detection mode.Feature: Digital tube is 0.36 inch 4-bit\nintegrated cathode digital tube Common cathode Only need three IO ports can\ndrive 8 bit digital tube The module compatible of 5V \/ 3.3V microcontroller\n(51 \/ AVR \/ STM32...) PCV board four corners of the fixed copper stud, which\ncan effectively precent short circuit accidents happen Wiring instructions (a\nprogram, for example, you can pick any IO port definition can be modified in\nthe program): VCC to 5V, GND to GND, DIN to P00, CLK to P02, CS to P01Note:\nVCC and GND do not reversed, it would burn the chip. 51 MCU P0 port requires\npull-up resistor, if your device does not have a pull-up resistor can be\nconnected to other ports data lines.Package Including: 4  MAX7219 8 bit\ndigital display module\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eMAX7219 is an integrated serial input \/ output common-cathode display driver, which connects your microprocessor to a 7-segment digital LED display with 8 digits; MAX7219 digital display control module, you can use it for Ar-duino.\u003c\/li\u003e\n         \u003cli\u003eThe module is compatible of 5V \/ 3.3V microcontroller; Only three IO ports are used to drive the eight digit display.\u003c\/li\u003e\n         \u003cli\u003eOnly three IO ports are used to drive the eight digit display.
