CoCocina 5Pcs 4 Digit 7-Segment 0.56' Led Display Tube Decimal 7 Segments Ht16K33 I2C Clock Double Dots Module Geekcreit for Arduino - Products That Work with Official Arduino Boards
CoCocina 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 have to do is write data to it using the 2-pin I2C interface. || There are three address select pins so you can select one of 8 addresses to control up to 8 of these on a single 2-pin I2C bus (as well as whatever other I2C chips or sensors you like).
