Square SunRobotics LED Dot Matrix Display Module MAX7219 & LED Matrix Display 8x8 Size 32x32 mm

1. Max7219 is a serial input or an integrated output common cathode display drivers, 7 segment digital led which connects the microprocessor with 8 bit digital display, can also be connected bar graph display or 64 independent led. It include: S an on-chip b bcd encoder, a scanning circuit, some words to drive, but also the static ram a 8 x 8 to store each data. Only an external register is used to segment the current settings for each led. A simple four wire serial interface can be connected with all general microprocessor. Each data can address does not need to rewrite all display update.
Features:

• 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.

These Displays are always in high demand in the DIY community as well as in Industrial Projects due to their multipurpose uses and cheap cost.

FEATURES:

• Single module can drive an 8 * 8 dot matrix common cathode
• Module Operating voltage: 5V
• Module dimensions: length 3.2 cm X 3.2 cm wide X 1.3 cm high
• Holes with four screws, diameter 3mm
• Modules with input and output interfaces, support for cascading multiple modules
• Integrating serial input/output common cathode display driver, connects microprocessor to 8-digit or 7-digit LED display, bar graph display and 64 red LED.
• When only control a single module, just need to connect the input port to CPU.
• When connect more modules, input port of the first module should connect CPU, onput port of that connects the input port of the second module, and the onput port of the second module connects the input port of the third module, and so on.
• VCC connects to 5V
• GND connects to GND
• DIN connects to P2.2
• CS connects to P2.1
