SEEU. AGAIN 4pcs 8-Digit 7 Segment Module MAX7219 8 Bit Digital Segment Tube LED Display Module Supports Cascade Eight Bit Serial 3 IO Ports 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.
  • MAX7219 digital display control module, you can use it..
  • The module is compatible of 5V / 3.3V microcontroller.
  • Only three IO ports are used to drive the eight digit display..
  • 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 (a program, for 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 do not reversed, it would 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..
