5Pcs MAX7219 Red 8 Bit Digital Tube LED Display Module For Arduino MCU Description: MAX7219 is an integrated serial input / output common-cathode display drivers, which connects the microprocessor and 8 bit 7-segment digital LED display, you can also connect a bar graph display or 64 separate LED. Includes an on-chip type B BCD encoders, multi-channel scanning loop, segment word driver, but also a 8x8 static RAM that stores each data. Only one external register is used to set the current of each LED segment. A convenient four-wire serial interface can connect all common microprocessor. Each data can be addressed in the update without rewriting all displays. MAX7219 also allows the user to select each data encoding or no coding. The entire device includes a 150μA low-power shutdown mode, analog and digital brightness control, a scan-limit register allows the user to display 1-8 bit data, there is an all LED light detection mode. Feature: 0.36 inch Common cathode Only need three IO ports can drive 8 bit digital tube The module compatible of 5V / 3.3V microcontroller (51 / AVR / STM32...) PCV board four corners of the fixed copper stud, which can effectively precent short circuit accidents happen Wiring instructions (a program, for example, you can pick any IO port definition can be modified in the program): VCC to 5V, GND to GND, DIN to P00, CLK to P02, CS to P01 Note: VCC and GND do not reversed, it would burn the chip. 51 MCU P0 port requires pull-up resistor, if your device does not have a pull-up resistor can be connected to other ports data lines. Package included: 5 x MAX7219 8 bit digital tube module 20 x Copper pillar 20 x Screws

5Pcs MAX7219 Dot Matrix Module MCU LED Control Module Kit For Arduino Specifications: A single module can drive an 8 x 8 common cathode lattice Operating voltage: 5V Size: 5 x 3.2 x 1.5 cm (L x W x H) LED color: Red With four screws hole, aperture 3mm With input and output interfaces, supports multiple modules cascade Wiring instructions: 1. The module left side as an input port and the output port on the right 2. To control a single module, just connect the input port to the CPU 3. When cascading multiple modules, the input port of the first module connect to the CPU, the output port connect to the input port of the second one, and so on. In the case of 51 MCU: VCC → 5V GND → GND DIN → P22 CS → P21 CLK → P20 Note: 1. VCC and GND is not reversed, it would burn the chip! 2. When the 51 microcontroller P0 port controlling, must be connected to the pull-up resistor, it is recommended that the resistance of 4.7K--10K 3. Please install lattice into the round hole first, and then insert the round hole to PCB board and weld. Face the side of lattice with words, from left to right pin order is 123456. PCB board 1st pin is square pad! 4. Electrolytic capacitors long-pin as positive, short-pin as negative; ceramic capacitor hsa no positive and negative points Package included: 5 x LED module 5 x Dupont line (5P-20cm)
