Draws close to 100 mA with full brightness and all segments displaying, so make sure you aren't powering it directly off your microcontroller pins. I powered it with a separate 5V source, with common ground. Default I2C address is (0x70). The I2C backpack is so nice, eliminating the need for lots of wires. The display is red and very bright at the top brightness setting. I did a quick test of it with an Arduino. I had a potentiometer analog output displayed (0 to 1023) and the brightness determined by the same potentiometer output. Brightness settings from 0 to 15, in the library I used worked great (see picture). The I2C backpack uses the HT16K33 chip, so any library compatible with that chip should work.
