MAX7219 Dot Matrix Module MCU LED Display Control Kit


The MAX7219 is an integrated serial input / output common-cathode display driver, it is connected to a microprocessor with 8-digit 7-segment digital LED display can also be connected to the bar graph display or 64 separate LED. On B BCD encoder including an on-chip, multi-channel scanning loop word drive, but also an 8 x 8 static RAM is used to store each data. Only one external register is used to set the current of each LED segment.

The LEDs are RED on this unit.

Module parameters:

A single module can drive an 8 * 8 common cathode lattice
2 module operating voltage: 5V
Module size: 5 cm in length X width 3.2 cm x 1.5 cm

Wiring instructions:

Module on the left as an input port, output port on the right.
Control of a single module, simply input port to the CPU
3 more modules cascade input termination module of a CPU, 2 output termination module input and output of the two modules is terminated with the input end of the first three modules, and so on. ..
51 MCU, for example:
VCC → 5V
DIN → P22
CS → P21
CLK → P20
Package Includes: 1 x MAX7219 dot matrix module (LED colour RED)
