Most LED displays like this are multiplexed - meaning that each digit is lit up in turn. So each digit is only lit for 1/4 of the time. This display however, is powered by two CAT4016 LED driver ICs, and although it has a nice synchronous serial interface, it lights all digits all the time. So this display is nice and bright. Of course you can dim it down by applying PWM to the BLK (blank) pin, but at least you have the flexibility of having some serious brightness if you want. The CAT4016 provides a constant current supply to the LEDs and can be powered from 3.3v to 5v all with the same levels of brightness.
This module is pre-built and requires no
construction, except for adding breakaway headers or soldering wiring directly
to the board and contains red LED digits.
