This display module is based on the TM1637 display controller chip and is available with red, green or blue .056" digits and either decimal points or a colon for clock applications.

The module runs from a 5 volt supply and the interface is two wire serial, similar to, but not compatible with I2C. There are several libraries available on the web to drive TM1637 display modules for both Arduino and Raspberry Pi. A link to our favorite Arduino library is in the resources section below.

External 4.7K pull up resistors on the CLK and DIO are required for most applications and are included with the module.

Brand-name TM1637 November 4, 2018

Can be hard to find quality (non-knockoff) TM1647 displays in 0.56".  These are the real deal and they work great!

Great quality and simple September 17, 2018
By: Dan Breen from Florence, MA United States  
I was fiddling with bare 7-seg displays but they're a pain to use with all the pins and having to write a driver...but this product solved all of that headache, providing a very easy to use 2-wire interface. There are Arduino libs for it already, and MicroPython. It was trivial to port to CircuitPython as well. The display looks great and it was well worth the price.
