MAX7219 for rescue when You need to display some text from Arduino. Soldered, mounted - ready to work. Green LEDs 8x32.
On stock: 23
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.
From all MAX7219 powered 8x32 LED modules this green one LEDs are not so bright like red or blue ones…
Libraries:
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.
