AZDelivery 4 Digits 7 Segment Digital Tube TM1637 LED Display Module with Clock Display compatible with Arduino and Raspberry Pi including E-Book!

One was flickering and showing random illuminations when the cables moved, the issue was one of the 4 pins wasn't soldered to the board.

As a beginner, the datasheets that come with this seem to have information about the display/interface board, but not much information on how to interface with it. Luckily, I downloaded the 7" Segment Display - 4 Digit - Deutsch 4 Digits 7 Segment Display DE.pdf" from their website and was able to find what library to download along with some example code which made it easy to use (download the TM1637 add in by Avishay Orpaz). You can then use the .h file to figure out how to do what you want. The need for a slightly better english guide is all that knocks this down a star- the display is bright and easy to use.

Decent display, but the description says it is and I2C display (AZDelivery 3 x 4 Digits 7 Segment Digital Tube TM1637 LED Display Module I2C), which it is not, hence 4 stars instead of 5. Not really a problem as it is easy enough to use it with the TM1637 Arduino library, but an updated description would be welcome.

quality build,the only difficulty i had was getting the ebook from the site.using this as a project/ learning piece on an arduino mega and worked well.moving up to the 8 digit version as i need more numerals.recommend AZ-Delivery items :-)

No easy way to write a single digit to any position

Good fast service works well

Decent enough although I'd have preferred the pins to be supplied separately. I want them mounted on the back of the board so now need to desolder. Also smaller than the pictures imply.

These worked perfect with Arduino nano no problems !
