This module is a 4 digit alphanumeric display with high brightness and red backlight, each digit is consists of a 14-segment digital tube. The commonly used 7-segment display, such as our Grove - 4-Digit Display can only display the numbers 0-9 and a limited number of letters. In contrast, the 14-segment digital display does not have this limitation, it can display all the characters, that's why we call it alphanumeric display.
Usually, the 14-segment display needs to use 17 or more wires to control the display, which means that a large amount of IO of your main control board (such as Arduino) will be occupied. With the help of on-board HT16K33 chip and Grove connector, we made it an i2c display, only four wires are enough. No troublesome soldering and no complicated wiring

Finally, a perfect large size! Exactly what I needed.
Color: Black
I am incredibly satisfied with the size of this holder! It’s rare to find an option this large on the market, and the extra space is exactly what I prefer. It holds everything perfectly and keeps my sink area so organized. If you prefer a larger size like I do, you won't be disappointed!

Perfect fit!
Color: Black, Color: Black
It is exactly what I needed. I love the expansion option and the toolbox that can be attached to the outside of the tray. I had a problem with the tray sliding after I adjusted to the size I wanted, but I secured everything in place with a few z-ties, and it works great. I also put anti-slip dots on the bottom, so it doesn't slide on the counter. I love it and I am very happy with my purchase!
