MAX7219 Dot Matrix Assembled Module MCU Control LED Display For Arduino
100% brand new and high qualitySize:50mmx32mmx15mm/1.95"x1.25"x0.58"(inch) (approx)
Module operating voltage: 5V
A single module can drive an 8 * 8 common cathode lattice
With four screws hole, aperture 3mm, by using our M3 Tongzhu fixed.
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.
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
