Specification:

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

Ⅳ.PIN Define
Pin Function
CLK Serial-Clock Input. 10MHz maximum rate.
CS Chip-Select Input. Serial data is loaded into the shift register while CSis low.
DIN Serial-Data Input. Data is loaded into the internal 16-bit shift register on CLK’s rising edge
DOUT Serial-Data Output. The data into DIN is valid at DOUT 16.5 clock cycles later. VCC Positive Supply Voltage. Connect to +5V.
GND Ground
