    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
