Led Matrix Schematic. The module makes use of the max7219 serial matrix led driver which handles all the complicated stuff such as multiplexing the leds and driving them at the correct currents. Also there would be no persistence of vision as any one of the row may light up or entire matrix not lighting up at all.
There are four leds across the length width and height. Also there would be no persistence of vision as any one of the row may light up or entire matrix not lighting up at all. As it can be seen the led matrix is composed of coumns made up of anodes and rows made up of cathodes if the leds connecting the rows even via resistor will damage the ic due to currents flowing beyond permissible range.
Also there would be no persistence of vision as any one of the row may light up or entire matrix not lighting up at all.
Here we have shown the pin configuration of 1388a led matrix module different modules may have different pinout configuration but they have same functioning pins. Led matrix modules are available in different modules and each module will have different pin configuration. Here we have shown the pin configuration of 1388a led matrix module different modules may have different pinout configuration but they have same functioning pins. Also there would be no persistence of vision as any one of the row may light up or entire matrix not lighting up at all.
