Excellent display for the money!
I was skeptical about using this display at first since the datasheet was a bad translation of Chinese to English. However, after looking over the datasheet and trying some things I was able to get the display working very well. I am able to accurately control each individual digits as well as the colon in the middle. The colon is the 'decimal point' of segment 2. I bought 6 of these since I know I will eventually use them and they work so well. I opted to use an MSP430 microcontroller to develop the controller on.

5.0 out of 5 stars Great displays, great price, S L O W
Reviewed in the United States on July 30, 2020

Update: The SoftwareSerial library is interrupt driven under the covers and that causes the 1637 updates to stutter resulting in long delays doing 1637 writes. This only happens if there is serial data arriving at the moment the 1637 write is occurring. To avoid this problem put a port.end() just before your 1637 writes and a port.begin() right after them. Serial gps data arriving at 9600 baud is unaffected at least for me - I only use GPRMC messages and discard everything else anyway so some of them might be affected but I don’t see any affect at all, except all of my 1637 writes now happen in 16–20ms.

Original review:

The 1637 part takes about 75ms per digit to write to on a nano. That is S L O W. They’re fine for clocks but not for anything with much else going on.

These go in all my temp projects, the gps test clock, the portable lux meter, the square wave clock generator, the rf24 transmitter and receiver test fixtures, etc. They’re a little small for across-the-room viewing but are 1/4th the price of the Adafruit units.

4.0 out of 5 stars Easy to use and very easy to read, but only intended for use as a clock

I ordered 2 of these 4 digit LED modules to display battery voltage and current on my RV. They are very easy to use with the Arduino IDE and microcontroller and look great. However they are intended to display time with a colon in between the digits and don't have any decimal points. I have ordered a set of the display modules with decimel points instead if a colon for the finished product. Great display modules but Just beware these are only for time (or integers) and won't display any decimal values.Very easy to use with the AM1637 library on github.

5.0 out of 5 stars Works as expected on Raspberry Pi with many Python libs available

Used it on two Raspberry Pi projects. One was a Raspberry Pi 2 and the other a Zero. For one I used it as a scrolling display on a MIDI keyboard and for the other I just displayed temperature and humidity data. I used the Adafruit Python libraries to drive it in both cases. There are plenty of Python libraries available for 7 segment displays on Raspberry Pi.

The displays are bright and work as expected. What else could you want?

5.0 out of 5 stars Small and easy to use
Reviewed in the United States on October 17, 2018

I love these little guys. They easily interface to Ardunio using two GPIO pins. It’s a two wire interface not based on I2C, but something proprietary. Using the tm1637.h library there’s a single command to specify the CLK and DIN pin assignments. I used one in a countdown reset timer I recently built based on an ATtiny84. There are plenty of code examples on the Internet and YouTube. I bought several more for future projects. Note that this display has 4digits and a colon between the 2nd and 3rd digits. There are no decimal points.

These are great. Small 7 segment 4 digit LED display that works well with Arduino boards. My only complaint is that if you buy another brand that looks similar the mounting holes may not exactly match up.
