Mini Digital Tube LED Display Module for MCU Arduino 7 Segment 1-8 Bit Display.

The MAX7219 module is an integrated serial input/output common-cathode display driver, connecting the microprocessor and 8-bit 7-segment digital LED display, and 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. It also allows users to select each data encoding or no coding.
  • The entire device includes a 150 μA low-power shutdown mode, analog, and digital brightness control.
  • With a scan-limit register to allow the users to display 1-8 bit data.
  • An integrated serial input/output common-cathode display driver, connecting the microprocessor and 8-bit 7-segment digital LED display, and can also connect a bar graph display or 64 separate LED.
  • With an on-chip type B BCD encoders, multi-channel scanning loop, segment word driver, and an 8 * 8 static RAM for storing each data.
  • Only one external register is used to set the current of each LED segment.
  • Only need three IO ports to drive 8-bit digital tube.
