YS-50 MAX7219 Single Dot Matrix Modul Display - Merah

MAX7219isan integrated serial input/output common-cathode display driver. It connects a microprocessor and an 8-digit 7-segment digital LED display. It can also connect to a bar graph display or 64 independent LEDs.its
It includes an on-chip B-type BCD encoder, multiple scan loops, segment word drivers, and an 8*8 static RAM to store each data.Only one external register is used to set the segment current of each LED.
A convenient four-wire serial interface can be connected to a general-purpose microprocessor.Each data can be addressed without rewriting all the displays when updating.MAX7219 also allows users to select encoding or not encoding for each data.
The entire device includes a 150A low-power shutdown mode, analog and digital brightness control, a scan limit register allowing users to display 1-8 bits of data, and a detection mode that allows all LEDs to emit light.
It requires only3GeIOports to drive1dot matrix!No flicker during dot matrix display!Support cascading!
Module parameters:
1. Asingle module can drive an8*8common cathode matrix
2.Module working voltage:5V
3.Module size: length3.2cmXwidth3.2cmXheight1.3cm
4.With4fixing screw holes,3mmdiameter
5.Module with input and output interface, support multiple module cascade
Wiring instructions:
1. Theleft side of the module is the input port, and the right side is the output port.
2. Whencontrolling a single module, you only need to connect the input port to theCPU
3.When the plurality of cascaded modules, the firstoneinput termination module tothe CPU, the output end of thetwoinput module, the firsttwooutput termination module of3input modules, and so forth. ..
