MAX7219 Dot Matrix Module LED Display DIY Kit SCM Control Module for Arduino PI
Description:
Seamless splicing and so that the dot matrix c--an be flexible spliced
Common cathode with bright dot matrix(8*--8), display fresh and brilliant picture.
A screen roll freely, to achieve the perfect pi--ture display
Since the master chip is used in Max7219 to- make product have the
Following characteris--tics :
The transmission efficiency of up to 10MHz.
Can be individually controlled for each point.
Lowest power consumption of 450uA (one m--odule).
Power-on reset automatically display full black
Serial communication, a great saving of MCU IO, also can be extended To expand the prog--ram with SPI.
For each screen brightness control, by setting the Max7219 instructions.
Application:Education,DIY, Robot,etc
