MAX7219 Dot Matrix Module Control Display Module DIY kit Cascade - Designed by ICStation.com

MAX7219 Dot Matrix Module Control Display Module DIY kit Cascade

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).Power-on 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.  

Ⅱ.Application: Education,DIY, Robot,etc.

Ⅲ.ABSOLUTE MAXIMUM RATINGS

• Voltage (with respect to GND) V+: -0.3V to 6V

• SEGA-G, DP Source Current: 100mA
• Continuous Power Dissipation (TA=+85°C) Narrow Plastic DIP: 0.87W
• Wide SO: 0.76W
• Narrow CERDIP: 1.1W
• Operating Temperature Ranges(Max7219) MAX7219: 0°C to +70°C
• Storage Temperature Range: -65°C to +160°C
• Lead Temperature (soldering, 10sec): +300°C 

Ⅳ.PIN Define

• CLK: Serial-Clock Input. 10MHz maximum rate.
• CS: Chip-Select Input. Serial data is loaded into the shift register while CS is 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.
