5Pcs 0.56 LED Display Digital Tube Clock Module 4 Digit LED 0.56 inch Display Time Clock Indicator Tube 7 Segments Double Dots TM1637 White Color

I used these to make a small digital desk clock based on an ESP32. Time is obtained through an NTP server. I like the programmable dimming function as well as the flexible of display formats. So far, it has worked perfectly and I would not hesitate to purchase for future projects.

Dots do not work. I was expecting a green display but it turned out to be a more yellowish color.

One of them didn't work, right out of the box. There was also a strip of pins missing from the pack, no big deal seeing as I had a dead unit.I'm using the Grove 4-Digit Display library and it works GREAT.The underside has "White Blue Green Red Yellow" printed on it, not sure what that's about - maybe just a generic board to which they attach the LEDs.I'd probably buy these again if the need arose especially at around $2 each (if they all worked).A pair of these should serve me well with my homemade MIDI Channel Changer project as I'll be able to display the incoming and outgoing channels at the same time and still be able to read it with my old eyes. and LCD works, too, but it's so much smaller.

Digital led works perfectly and easy to use

They work but I've had multiple displays just not work

The modules seem to work ok. The issue I have is the DPs do not work. I really needed decimal points for my project and this seems to be a common issue with most of these modules.

They work but why are there no decimal displays? With these only the clock bits work.
