Easy 8-digit seven segment LED display with serial interface

Seven segment LED displays are brighter, more attractive and provide a far viewing distance as well as a wider viewing angle as compared to LCD displays. The major drawback of using seven segment LEDs is they are resource-hungry. Time-division multiplexing is the most common technique of interfacing 7-segment LEDs to microcontrollers. With this technique, an 8-digit seven segment LED display with the decimal point requires at list 16 I/O pins of the microcontroller, which is quite a lot. Consequently, their use with low pin-count microcontrollers (such as PIC12F series) is not practically feasible. SPI7SEGDISP8.56 is our latest version of the MAX7219 based serial seven segment LED display module that will allow you to add 8 digits of seven segment LED displays to your project using only 3 I/O pins, and provides full control of all the digit segments including decimal points. You can even cascade two or more of these modules together without sacrificing any extra I/O pin.

Please note that:

1. You will receive an assembled and tested board.

2. LED displays included in this kit emit green color. They are 0.56" modules. If you need yellow or red color LED displays, there is a separate listing for them. Go to our store to find the right one. It is mentioned in the product title.

Two or more SPI7SEGDISP8.56 modules can be cascaded together easily. Read the document page for further detail.

I expected 0.36 inch digits, but i got gigantic digits

I expected normal 0.36 inch digits, but i got gigantic digits. So I can not use it for anything.

The product works great

This worked great. Though I blew up one connecting it to 5v line instead of 3.3v. It is not listed in the doc what the voltage of VCC should be.

In case any one needs to know it is 3.3v.

Response from Embedded Lab | June 21, 2017

Hi Matthew,
It works safely at both 5V and 3.3V. If you blew up one, the reason might be something different.

Thanks,
Raj

Flat out awesome, great support

I bought 5 displays and absolutely love them. They're very easy to use and look great. The seller was great to work with and supremely helpful in resolving issues. One of my displays was mounted at a slight angle and he fixed it for me. I also requested one of the dual-row displays in a color which wasn't listed and he was happy to accommodate. The only negative thing I have to say is that the double row display is a slightly different color than the rest due to lot differences in the display modules — not something that will impact most orders, but something to be aware of if you are ordering custom items.

Excellent!

The display area is large, but the footprint is small. Good design. There are few component parts and soldering is easy. I can save the number of pins, thanks to the SPI connection. Thank you.
