Feature

●Module operating voltage: 5 V
●Use high-quality chip, integrate BCD encoder, scan circuit and driver circuit internally
●The chip occupies only 3 IO ports that can be cascaded. Built-in scan circuit in the chip, does not occupy system resources; Built-in analog and digital brightness control, consistent brightness display at each point
●Internal built-in static RAM, each data can be addressed during the update without changing all displays
●Package contents: 2 x 8 x 8 green light LED display module, 1 x 11.8 inch female-male Dupont cable 10 pin


Description

Specification:
Single module can drive an 8 x 8 dot matrix common cathode
Module operating voltage: 5 V.
Module dimensions: 3.2 x 3.2 x 1.3 cm / 1.26 x 1.26 x 0.5 inches (L x W x H).
Holes with four screws, diameter 3mm
Modules with input and output interfaces, support for cascading multiple modules

Wiring instruction:
On the left block to an input port, an output port on the right
When the control of a single module, simply enter the port received a CPU
When more than 3 modules cascaded output input termination CPU, the input output termination module of the first two modules of the first one, the first two modules of the termination input terminal of the three modules, and so on

Taking 51 single chip microcomputer as an example:
VCC - 5 V.
GND - GND
DIN - P22.
CS - P21
CLK - P20

Package includes:
2 x 8 x 8 green light LED display modules.
1 x 11.8 inch female-male Dupont cables, 10 pin.
