Description

There is four 7 segment display inside of this module, with a PCB control back board.

See the pictures about how it looks like.

Features:

  • Standard 5135 enclosure, nice look, easy to install on devices. The mounting hole dimension should 72*39 mm, and you need leave two extra cutout place for the “ear” on the side of the panel.
  • All these four seven segment display controls by 4 pieces 74HC595 ICs where are on the back PCB board. All the segment display are current limited.
  • Static driven, when the number is not changing, MCU don’t need to refresh it, save MCU resources.
  • Simple interface: +5V, -5V, data, data shift  CLK, latch LCK, only need 3 wires to MCU, save resources.
  • Can connect in series, e.g. four displays, can connect one by one, and only connect the three wires of the first display to MCU is enough.
    • VCC, GND, SDI – DATA in, SCK|CLK – clock, RCK|LCK latch lock
  • If you don’t need enclosure, there are four screw holes, easy to install too.
  • Can display the dot symbol.
  • Needs 300mA to display 8888, because the high brightness.

    The only reason I am giving this 1 star is because I can’t give it 0. This product is a complete rip-off of the original and does not work with the provided demonstration links. It displays the characters in reverse order. Look for the original and avoid this product.

    I initially gave this product a 1 star rating because it didn’t look like the one in the image nor did it work the same. After contacting the company I found out that there are 2 versions, one is the Green PCB (shown in product image), and the other is a Red PCB (the one I received). They are the same product, though with one slight difference, the order the digits display. The Green PCB displays the digits in reverse order 4, 3, 2, 1 and the red PCB displays as digit 1, 2, 3, 4 –

    Green PCB
    digitalWrite(latchPin, LOW);
    shiftOut(dataPin, clockPin, LSBFIRST, LED_SEG_TAB[d]);
    shiftOut(dataPin, clockPin, LSBFIRST, LED_SEG_TAB[c]);
    shiftOut(dataPin, clockPin, LSBFIRST, LED_SEG_TAB[b]);
    shiftOut(dataPin, clockPin, LSBFIRST, LED_SEG_TAB[a]);
    digitalWrite(latchPin, HIGH);

    Red PCB
    digitalWrite(latchPin, LOW);
    shiftOut(dataPin, clockPin, LSBFIRST, LED_SEG_TAB[a]);
    shiftOut(dataPin, clockPin, LSBFIRST, LED_SEG_TAB[b]);
    shiftOut(dataPin, clockPin, LSBFIRST, LED_SEG_TAB[c]);
    shiftOut(dataPin, clockPin, LSBFIRST, LED_SEG_TAB[d]);
    digitalWrite(latchPin, HIGH);

    The module is an excellent display for lots of Arduino projects, it is cheap, clear to read and has an enclosure. Would highly recommend!
