### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Display works fine.
  

*by F***R on Reviewed in the United States on May 18, 2023*

I used it for a rotary encoder reader to mesaure angle with a R02040 Pico. It worked fine, just a little bit slow due to the use of I2C. Nice brightness and easy to set up.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Nice Display For Time-Date-Temp
  

*by D***O on Reviewed in the United States on November 15, 2023*

It interfaced perfectly with my "Arduino UNO REV3_A000066".  I'm able to display the date, day, time and temp in fairly large letters.  I like the contrast adjustment that helps the text stand out clearly.  I've been using it for several months now and, so far, so good.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works Well
  

*by M***D on Reviewed in the United States on February 16, 2023*

Same library and commands as the smaller 16X2 that comes with the Arduino starter kit.
