Hello.
I am looking for a turn key solution to convert something that produces 8 bits of data to I2C.
Pretty much I am trying to connect a module like this:

to my Arduino via I2C. What am I shopping for?
Thank you.

Or try explain once more what you are looking for.
The board appears to already have I2C using two pins near the left side, SCL and SDO. The eight 'Out' pins may be a pair of four to read the row/column matrix. The data sheet, if you can find one, should have the details. You will also need a library for the I2C functions.
