Your cart is empty. 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.
Specification:
- Size: Approx. 5.03 x 2.68 x 1.2 cm/2 x 1.1 x 0.5 inch
Package Includes:
10 Pieces 0.56" 4 Digit LED Display Modules
Note:
Color might be slightly different due to the color calibration of each individual monitor.
Please allow slightly measuring deviation due to manual measurement.

Prompt arrival, inexpensive, and all 10 displays tested 100%. These are hardware and software compatible with the treedix displays I reviewed earlier, featuring 4 digits+decimal points and a center colon for clock/time readouts. Based on the HT16K33 controller, configured as 5 digits, the colon being the middle “digit†D-D-C-D-D where D is a 7-segment digit and C is the colon.
