A convenient four-wire serial interface can connect all general-purpose microprocessor. Each data can be addressed in the update does not need to rewrite all the display. MAX7219 also allows the user to select on each data coding or non-coding.The entire device contains a 150μA low-power shutdown mode, analog and digital brightness control, a scan-limit register allows the user to display the 1-8 bits of data, as well as a let all LED light detection mode.
Only need three IO ports can drive a dot-matrix! Dot-matrix display, flicker-free! Supports cascading!

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
GND → GND
DIN → P22
CS → P21
CLK → P20
A single module can drive an 8 * 8 common cathode lattice
Module operating voltage: 5V
Module size: 5 cm in length X width 3.2 cm x 1.5 cm
4 with four screws hole, aperture 3mm,
Modules with input and output interface, thus supports multiple cascaded modules
