10sets MAX7219 Dot matrix module MCU control Display module for Arduino
1.A single module can drive an 8 * 8 common cathode lattice
2.Module Operating voltage: 5V.
3.Module size: 5 cm long X 3.2 cm wide X 1.5 cm high
4.With four screws hole, aperture 3mm, by using our M3 Tongzhu fixed
5.Module with input and output interfaces, supports multiple modules cascade
1.The module left as an input port to the output port on the right.
2.The control of a single module, simply input port to the CPU
3.Multiple modules cascade input termination CPU, 2 output termination module, a module of the input of the input terminal, the output terminal of the first two modules of the first three modules, and so on ...
51 MCU, for example:
VCC → 5V
GND → GND
DIN → P22
CS → P21
CLK → P20
Package: DIY kits
1x PCB board
2x 5P bent pin single row pin
1x 24P IC socket
The 1x Inline MAX7219 chip
1x 10uF electrolytic capacitor
1x 0.1uF ceramic capacitor
1x 10K resistor
2 Block 2x 8P round hole (pitch 2.54mm)
1x 3mm 8 * 8 common cathode red dot
1.VCC and GND is not reversed, it would burn the chip!
2.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.
3.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!
4.Electrolytic capacitors long-legged as positive, negative short legs; ceramic capacitor without the positive and negative points
