Very nice Red LED 4 digit displays. I use them in a bussed configuration connected to a microcontroller and displaying 8 separate digital values. The displays are very bright, normally I use them at half brightness. It is important to know the solder jumpers which control the address are on the back, 1 bottom 2 middle and 4 top.

Works as expected. LED display is already soldered to the I2C backpack, but I2C header pins have to be soldered to the board.
