These are not UL certified and the label doesn't match that shown in the picture.

Are these UL certified?

I had I2C working using an Arduino Nano. I2C addresses are 7 bits. The 8th bit determines whether it's read/write. So to write, send 11100010 not 01110001; to read, 11100011.

The Eagle file schematics here and on github are incorrect and don't agree with the Schematic link (http://dlnmh9ip6v2uc.cloudfront.net/datasheets/Components/LED/Serial-7-Segment-Display-v31.pdf), which is correct. For instance, segment A is on PB0 not PD6, segment B is on PC0 not PB0, etc.
