    Very easy to use, runs nicely on 3.3V, and the brightness is controllable in software. I used the TM1637Display library on an Arduino Pro Mini (3.3V), and using the example code I was easily able to incorporate it as the display in a little receiver that uses an nRF24L01 to get information from a weather station in my garden.

    It looks robust, the digits are 10mm tall, it’s very inexpensive, and it’s easy to use.
