Generic 10x 7-Segment 4 Digit Display Module Digital Clock with Adjustable, 5.03 x 2.68 x 1.2 cm, Red

Description: - These 7-segment displays normally require 13 pins (5 characters and 8 total segments each). - Solves the annoyance of using 13 pins or a bunch of chips by having an I2C constant-current matrix controller sit neatly on the back of the PCB. - The controller chip takes care of everything, drawing all the LEDs in the background. - All you is write data to it using the 2-pin I2C - There are three pins so you 8 addresses to control up to 8 of these on a single 2-pin (as well as whatever other I2C chips or sensors you like). - chip can the entire display from 1/16 brightness up to full brightness in 1/16th steps. - It can't individual LEDs, only the entire display at once.
