MAX7219 8×8 Dot Matrix MCU LED Display Control Module Kit
MAX7219 Dot Matrix Module MCU LED Control Module Kit For Arduino
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
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
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
1 x LED module
5 x Dupont line (20cm)

As shown. These are good because when you connect them there is no gap like on some of the pre-mounted 4 display modules. Fast shipping to Canada compared to some others.
Well packaged, very fast delivery, the article is as described, thank you very much
Items got shipped quickly. Looks like the goods arrived in good condition. Did not have time yet to use them.
The contacts were bent, but it was easy to fix. It was a great disappointment that the size is smaller than the one I already had (it turns out, they are different)
I am very satisfied, fast delivery and good product quality.Thank you
