4Pcs MAX7219 8 Digit 7 Segment LED Tube Display Control Module for MCU/51/AVR/STM32

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..

Microprocessor & Smart Chip Designed For Recognizing & Optimizing The Charging Requirements Of The Electronic Device.
Charges Multiple tablets and High Power Devices At Once.
4 Vertical USB Ports Are Generously Spaced To Provide More Room For Maneuvering & Reducing Stress On USB Cables.
Compact Design Fits In A Standard Wall Box and Is Compatible With Standard Wall plates.

Automatically detects excess humidity in a room and activates the ventilation fan to lessen condensation which helps reduce mold and mildew, Sensor uses microprocessor and digital sensing technology to continuously monitor and manage humidity levels in a room.
Built-in timer sets the “minimum ON time” for the ventilation fan. The sensor time settings can be custom set to 10, 20, 30 or 45 minute intervals. The sensor will continue to operate the fan for the minimum time set or until there is a reduction in room humidity level.
A sensitivity level adjustment allows users to adjust the sensor’s sensitivity to ambient air to prevent false cycling.
Features an Air Cycle mode which automatically turns ON the ventilation fan for a set period of time and repeats the cycle hourly (eg. 20 minutes ON/40 minutes OFF each hour).
Replaces a single pole switch for control of ventilation fan or a fan/light combination, Fits in a standard wall box and requires a neutral for operation, The device’s built-in humidistat control meets CALGREEN requirements for Indoor Air Quality and Exhaust, Five-Year Limited warranty.
