Model Number : MAX7219Condition : NewType : ModuleBrand Name : SZYTF : Mainland China
MAX7219? it is an integrated Serial Input/ output common cathode display driver, it connects the microprocessor8 digits of7 segment digits LED display, you can also connect the bar line diagram display or64 an independent LED. It includes a piece B type BCD ener, multi-channel scanning loop, segment driver, and there is also one8*8 the static RAM used to store each data. Only one external register is used to set each LED the segments of the current.A convenient four-wire serial interface can connect all general purpose microprocessors. Each data can be addressed without rewriting all the display when updating. MAX7219 you are also allowed to select ening or non-ening for each data.The entire device contains a150μA low power consumption off mode, analog and digital brightness control, a scan limit register allows users to display1-8 bit data, and another one allows all LED luminous detection mode.Just need3 A IO port can be driven1 A dot matrix! There is no flicker when dot matrix display! Supports cascading!Module :1. A single module can drive one8*8 common cathode lattice2. Module working voltage:5V3. Module size: length 12.8 CM X width3.2 CM X high1.3 CM4. With 64 fixed screw holes, aperture3mm5. The modular belt Io interface to support multiple module cascadewiring instructions:1. The left side of the module is the input port, and the right side is the output port.2. When controlling a single module, you only need to connect the input port CPU3. When multiple modules are cascading,1 the input terminals of each module are connected CPU the output termination first2 the input of the module2 the output terminals of each module are connected to3 the input of modules, and so on...To51 single-Chip Microcomputer, for example:VCC→5VGND→ GNDDIN→ P2.2CS→ P2.1CLK→ P2.0invoice:1.MAX7219 dot Matrix module of four-in-one( finished product, with dot matrix, has been tested)2.20CM DuPont line 5P
