0.36 Inch PCV Board MAX7219 Red 8 Bit Digital Tube LED Display
Module Three IO Ports
Product Features:
1.Common cathode
2.Only need three IO ports can drive 8 bit digital tube
3.The module compatible of 5V / 3.3V microcontroller (51 / AVR /
STM32...)
4.PCV board four corners of the fixed copper stud, which can
effectively precent short circuit accidents happen
5.Wiring instructions (a program, for example, you can pick any IO
port definition can be modified in the program): VCC to 5V, GND to
GND, DIN to P00, CLK to P02, CS to P01
| Product Description |
| MAX7219 is an integrated serial input / output common-cathode
display drivers, which connects the microprocessor and 8 bit
7-segment digital LED display, you can also connect a bar graph
display or 64 separate LED. Includes an on-chip type B BCD
encoders, multi-channel scanning loop, segment word driver, but
also a 8x8 static RAM that stores each data. Only one external
register is used to set the current of each LED segment. |
| A convenient four-wire serial interface can connect all common
microprocessor. Each data can be addressed in the update without
rewriting all displays. MAX7219 also allows the user to select each
data encoding or no coding. |
| VCC and GND do not reversed, it would burn the chip. |
