TM1637 display with buttons and leds for Arduino

Who I am

Hi, My name is Joram and I'm a 3th year electrical engineering student from the Netherlands who likes to make projects at home, mostly projects which involve lighting / LED.


Project desciption

This display is made to connect to a DMX ledstripcontroller. because a display and buttons uses a lot of pins I decided to use a TM1637 module and extend the standard module with 4 buttons and 3 leds. the entire module is controlled by only two data lines (and power). In the link to the documentation you will find all documentation, schematic, gerber files, Bill of materials and a complete 3d model. This model is an upgrade of the first version and is a lot smaller and uses SMD components.


Words to PCBWay

The first versions of this projects were made with PCBs from PCBWays and they turned out great. PCBs were completed in 2 days and arrived a week later.Thank you!

  • Hello, I was looking at your project, and when compiling the code I get the following error: 'DMXSerial' was not declared in this scope. It seems to me that residual part of your code, which is not part of the essential code to use the plate. Or it could also be that I don't have the right library.
