    I am using it for my Attiny85 based tachometer. It is readable under daylight conditions. There is only one minor problem: I wish the unit would come without the connector. I must desolder it and sometimes the PCB can get damaged if I use too much heat.

    Have not tested it yet, but I’m sure it will make a nice clock.

    The Display is "must have" in any DIY or Profy electronics lab- for 3 d printers and other toys and gadgets

    Good module, but it needs constant refreshing. It does *not* have a memory, ie if you send "1234" and want the display to stay that way, you'd have to send it over and over again every n millisecs. What I dislike: the rectangular input header is pre-soldered, next to impossible to get it out and replace with straight headers without destroying the traces (done that recently). I would prefer if there was a version with unsoldered connectors... (for mounting it straight onto a board). Another hint: left and right connectors seem to have different functions, so beware!

    Received these products, and immediately ran into issues because I could not find a library to work with them. After many hours of research I finally found one, and I am happy to say it works great now. For those of you looking, here it is: I do however wish they had not soldered the 90 degree connectors onto these units. At least I wish they had soldered them so they were bending toward the bottom rather than up. I tried to take these out and solder some straight pins on them, but it was extremely difficult. I then tried to leave them and solder pins on the other side, but apparently the pins are different because it does not work. I have already ruined one trying to take out the existing pins.

    Works great with following code: digitalWrite(latchPin, LOW); shiftOut(dataPin, clockPin, LSBFIRST, b4); shiftOut(dataPin, clockPin, LSBFIRST, B10000000); digitalWrite(latchPin, HIGH); digitalWrite(latchPin, LOW); shiftOut(dataPin, clockPin, LSBFIRST, b3); shiftOut(dataPin, clockPin, LSBFIRST, B01000000); digitalWrite(latchPin, HIGH); digitalWrite(latchPin, LOW); shiftOut(dataPin, clockPin, LSBFIRST, b2); shiftOut(dataPin, clockPin, LSBFIRST, B00100000); digitalWrite(latchPin, HIGH); digitalWrite(latchPin, LOW); shiftOut(dataPin, clockPin, LSBFIRST, b1); shiftOut(dataPin, clockPin, LSBFIRST, B00010000); digitalWrite(latchPin, HIGH);
