Overview:
This 8x32 dot matrix display is composed of four interconnected 8x8 dot matrix modules, creating a versatile display panel. It uses the MAX7219 LED Driver IC for seamless operation, but the modules can also be split apart for individual use in separate projects.
The display operates at 5V and features 16 mounting holes (3mm each) for secure installation. It supports serial and SPI interfaces, allowing all matrices to be controlled via a single input. The output of each module connects to the input of the next, ensuring streamlined communication across the entire panel.
Features:
• 8x32 dot matrix display with four 8x8 modules.
• Operates via MAX7219 LED Driver IC.
• Can be used as a single panel or split into individual modules.
• Supports serial and SPI interfaces.
• All modules are controlled using a single input.
• Daisy-chain connection between modules for expanded functionality.
Specification:
• Operating Voltage: 5V DC.
• Dot Matrix Size: 8x32 (4 x 8x8 modules).
• Mounting Holes: 16 holes, 3mm each.
• Communication Protocols: Serial and SPI.
• Control IC: MAX7219 LED Driver.
• Module Size: 128 x 32 x 13mm
• Module Support: – Multiple Cascading Modules
• Interface: – Up to 10MHz Serial/SPI
Wiring:
• The left side of each module is the input port, and the right side is the output port.
• For controlling a single module or multiple modules, only the input port needs to receive signals.
• To cascade modules: Connect the CPU to the input port of the first module. Connect the output port of the first module to the input port of the second module. Repeat this pattern for additional modules in the chain.
