SoluMax7219 Dot Matrix LED Display DIY Kit SCM Control Module for Arduino Pic// Max7219 Dot Matrix Module MCU Control Display Module DIY Kit for Arduino//diy Max7219 Red LED Dot Matrix Display Module for Arduino

A convenient four wire serial interface can connect all general purpose microprocessor. Each data can be addressed in the update does not need to rewrite all the display. MAX7219 also allows the user to select on each data coding or non-coding. The entire device contains a 150uA low-power shutdown mode, analog and digital brightness control, a scan-limit register allows the user to display the 1-8 bits of data, as well as a let all LED light detection mode. Wiring instructions: module left for the input port, the output port. control of a single module, only need to input port for receiving a CPU Note: VCC and GND is not reversed, it would burn the chip When the 51 microcontroller P0 port control, must be connected to the pull-up resistor, it is recommended that the resistance of 4.7K--10K Please lattice into the hole first seat, and then inserted into the round hole Block PCB board welding. Lattice word side facing the surface order from left to right pin 123456. PCB board 1 foot square pad Electrolytic capacitors long-legged as positive, negative short legs; ceramic capacitor without the positive and negative points Package Includes : 1 x PCB board 2 x 5P pin sets 1 x 24P IC socket 1 x MAX7219 chip 1 x 10uf electrolytic capacitor 1 x 10kohm resistor 1 x 3mm 8 x 8 common cathode dot matrix *
