LED Module mit Uhren Display TM1637

in BASIC Stamp
I bought a
LED Module mit Uhren Display TM1637 on ebay.

I would like to use it with a basic stamp2.
I can’t find info’s for the Uhren Module, only for the TM1632.
May someone have Info’s or a link which helps me to start?
What kind of data I have to send and what kind of data I may resave?
I've searched the net but I'm stuck

    If I input TM1637, I get lots of links, including pointers to data sheet.

    I looked at the TM1637 data sheet and given a choice, I would choose the MX7219 over it any day: 
    1.  TM1637 supports only 6 digits vs. 8 for the MX.
2.  TM1637 does not  have a chip select meaning you cannot put it on a SPI bus with other devices.
3.  TM1637 does not do its own decoding meaning you have to have your own font.
4.  TM1637 does not have any BS-2 support.

    That said, the TM1637 does support a 16 key keypad.
