This board has it all : 8 red leds, 8 7-segment LEDs (plus decimal point) and 8 push buttons. It can be controlled by an Arduino (in my case a Arduino Mini Pro) by only 5 wires (including VCC and GND). The TM16380 chip has the possibility to chain multiple boards together, but I didn't try that (yet). Software (libraries) can be found at https://code.google.com/p/tm1638-library/ Be Aware : The leds are only red leds. I have a similar board (JY-MCU) from another supplier with bi-color leds. Getting started with it is easy if you just take a look at the reference document from the library. This is a basic board for further prototyping.

Fun LED display for any I2C controller, like the Arduino The Arduino libs are at https://github.com/rjbatista/tm1638-library This is a 5V board Datasheet here: http://www.datasheet4u.com/datasheet/T/M/1/TM1638-TitanMicro.pdf.html (in Chinese) I'm using it to emulate an old Tandy Microcomputer Kit from here http://microcontrollertrainer.blogspot.com/ The only complaint I have is that the colors of the wiring are not very different. All shades of blue/gray. Red, Orange, Black, White and Blue would have been better

Quality is good no major defects. Works fine I had to change some things in a library for Arduino to work correctly with an ESP8266. Runs fine from 5 or 3.3v

Function is OK and gives many possibilities.

Complete & independent control over all 7 segments, decimal point and auxiliary LED for each of eight segments. This allows for limited alphabetic characters (see photos). Be sure to use pull up resistor for reading keys. Unit is capable of reading any combination of key presses, so 256 possible input patterns are possible. However, with the standard library, I found the key reads to be a little erratic, so I stick to just single button patterns. For some reason, LED #1 lights at half brightness whenever one of the other LEDs is commanded on. The 2 LED banks are a bit mis-aligned, but this is just cosmetic. A real bargain to keep around for Arduino projects & tests.

Все дошло в целости и сохранности. Фото прилагаю. Снизу индикаторной платы - царапины, поэтому ставлю четыре "звёзды".

I received it on time I ordered it by banggood because it is the cheepest through Online shopping. Later on I will test it.
