  1. m.p (verified owner)

    I bought two of these and received them quickly and in good condition.

    They do exactly as advertised: eight buttons, eight 7-segment (with dot, so I suppose 8-segment?) displays, and eight LEDs. Works great at 5V, also works at 3.3V but is a little dimmer.

    Note that this is NOT an I2C or SPI bus device, it has its own pinout and command set. Still easy to use – libraries exist for Arduino, and the first one I tried (TM1638lite) worked like a charm.

    Well-built, all the buttons and LEDs work, and it took about three minutes from taking it out of the package to getting the buttons to show different letters on the display.
