LED 8x32 (red) matrix module driven by MAX7219

MAX7219 is 7seg LED display driver. But LEDs does have to be placed in 7seg style - so MAX7219 can drive 8x8 LED matrix. And MAX7219 chips can be joined in chains. Thus this 8x32 LED matrix - built from 4 modules placed side by side.

But - since MAX7219 chips can be joined even in longer strips - You can attach next modules to get even longer display.

Product image does not represent brightness and color of red LEDs. Without additional lighting module looks like this:

Specification:

• Size: 129 mm x 32 mm x 13 mm (height includes LED module, but not pins below PCB)
• Power supply: 5V
• Soldered 1x5 angle goldpin (IN side)

Set includes:

• LED matrix module 8x32
• F-F jumper wires, 20 cm, 5 pcs
• 1x5 angle goldpin to solder on OUT side

Libraries:

• MD_MAX72XX (chip interfae): MD_MAX72XX on Github
• MD_Parola (text, align, etc): MD_Parola

Using this libraries set MD_MAX72XX::ICSTATION_HW as hardware type.

Using this libraries set MD_MAX72XX::FC16_HW as hardware type. In case display is wrong (letters are reversed on each submodule) try other variants: MD_MAX72XX::PAROLA_HW, MD_MAX72XX::GENERIC_HW or MD_MAX72XX::ICSTATION_HW.

On Starter Kit we have post with example how to use this module.
