MAKER AND HACKER Max7219 Dot Led Matrix Module Mcu Control Led Display Module Display Lights Electronic Hobby Kit

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). · The transmission efficiency of up to 10MHz. · Can be individually controlled for each point. · Lowest power consumption of 450uA (one module). · Power-on reset automatically display full black · Serial communication, a great saving of MCU IO, also can be extended To expand the program with SPI. · For each screen brightness control, by setting the Max7219 instructions. ABSOLUTE MAXIMUM RATINGS · Voltage (with respect to GND) V+: -0.3V to 6V · DIN, CLK, LOAD, CS: -0.3V to 6V Current · DIG0-DIG7 Sink Current: 500mA · 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 PIN Define · 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. · GN:D Ground
