Overview

Product name: SPI7SEGDISP8.56-2R

SPI7SEGDISP8.56-2R is a MAX7219-based seven segment LED display board with 8-digits which are arranged in two rows of four. The MAX7219 allows you full control of all digits and decimal points through three I/O pins of a microcontroller. The communication interface is SPI-compatible. You can also control the brightness of the LED segments through software. Please visit my tutorial page for further details about MAX7219. The tutorial also describes how to interface this driver chip with PIC and Arduino to control the seven segment displays.

Features

3-wire SPI interface
Easy interface with Arduino using LedControl library
Operates at +5V
Multiples modules can be cascaded
16 levels of brightness control through software
Dual 0.56" 4-digit seven segment displays
Available in Red, Blue, and Yellow. This listing is for Blue LED.

Applications

Seven segment LEDs are brighter than LCD displays and provide a far viewing distance and a wide viewing angle. They finds application in front panel display boards of microwave ovens, washers and dryers, digital clocks, frequency counters, and many other gadgets. SPI7SEgDISP8.56-2R is suitable in many projects where you need to display two variable values simultaneously, such as displaying temperature and humidity, or current and voltage, etc.

Easy

I agree with Greg. With LedControl library I got it running in first try.
I am using this display in my heater_control project. I read several temperatures and alternate them in upper row. Electricity consumption, date and time are alternating in lower row. My project is still ongoing, it will have more measured streams while I proceed.
See https://github.com/kalliot/heater_control
Finally I realized how to control those decimal dots, too.

Double row 4-digit seven segment (Blue) LED display module w

This is a nice little seven segment display module driven by the max7219 chip. This module was easy to setup and program. In short order, I was able to interface it with my Arduino Mega SPI interface with two thermocouples. I am able to display a temperature on each row. This board looks good and is well made.
