Product Description

It can be extended without limitation.
Our item is with STM8S003F3 MCU which the data storge space is 1K.
If you need to show more characters which is up to 1K, you can change the MCU which is with larger space. And please be noted that the MCU and Display Module should be powered seperately.

1. Description

Ⅰ.Product Feature:

• Seamless splicing and so that the dot matrix can be flexible spliced .
• Common cathode with bright dot matrix(8*8), display fresh and brilliant picture.
• A screen roll freely, to achieve the perfect picture display
• Since the master chip is used in Max7219 to make product have the following characteristics:
• 1).The transmission efficiency of up to 10MHz.
  2).Can be individually controlled for each point.
  3).Lowest power consumption of 450uA (one module).
  4).Poweron reset automatically display full black
  5).Serial communication, a great saving of MCU I/O, also can be extended To expand the program with SPI.
  6).For each screen brightness control, by setting the Max7219 instructions.
