I am hoping some one here has come across this little board, I think it could be an I2C module for the keypad but am not sure. I can not seem to find anything on it, it came with the keypad in one of those 37 piece kits that I got a few years ago. Any help on this would be appreciated.  
I really like trying out some of the libraries and the examples that are posted here.  
Thanks

To-day I found some info by looking up the number on the I/C “TM1650” and found an arduino library for it on GetHub

> Arduino TM16xx library for LED & KEY and LED Matrix modules based on TM1638, TM1637, TM1640 and similar chips. Simply use print() on 7-segment and use Adafruit GFX on matrix. - GitHub - maxint-...

I have yet to try any of the examples as I am not that good of coder with the arduino IDE which is why I love the XOD IDE.
