MAX7219 is an integrated serial input / output common-cathode display driver, which connects your microprocessor to a 7-segment digital LED display with 8 digits.This module is compatible with 5V and 3.3V microcontrollers, and you you can use it.
Material: PCB+Electronic components, LED color: Red.
Only three IO ports are used to drive the eight digit display. MAX7219 supports flicker free displays as well as cascading displays. PCV board four corners of the fixed copper stud, which can effectively precent short circuit accidents happen..
Wiring instructions (take the provided program as an 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.
Digital tube is 0.36 inch 4-bit integrated cathode digital tube.
Note: VCC and GND should not be connected reversed, so as not to burn the chip.
51 MCU P0 port requires pull-up resistor, if your device does not have a pull-up resistor can be connected to other ports data lines..
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..

A chemical-free and maintenance-free way to purify water that eradicates suspended bacteria and algae in the water column that contribute to cloudy and green water, respectively.
Helps prevent the growth of cyanobacteria that often smothers and destroys aquatic plants and does not harm beneficial, surface-dwelling bacteria.
CCFL (Cold Cathode Fluorescent Light) technology runs cooler than traditional UVC bulbs to last up to 30,000 hours (3X longer).
Quickly connects in-line to all canister filter hosing with an internal diameter of 5/8” (or 16 mm), including all Fluval 07 and 06 Series Filters, Not for use with Fluval FX Series.
For use in freshwater, saltwater and even turtle aquariums where algae is often present.
