        ?LED display module 1.jpgLED display module 2.jpg

        ?

        Features:100% brand new and high quality8 Bits, 8 keys, 8 LEDs, 8 digital tubes, common cathode LED digital tube.With TM1638 Chip, this module gather more than three common SCM peripheral circuits.The advantage is only three IO ports will be occupied when it drives.SCM doesn't need to work for scaning display and key scaning.It only need to read the relevant register to send display data or test button so it save MCU resources effectively.Keys are sensitive and display effectively.Specifications:The rated voltage: DC12VVoltage range: DC7.0 V-13.6 VThe input power: 0.24 AThe rated speed: 9500 R.P.MTemperature range:-10-70CTxpect life: 25C L10 when expected life 50000 hoursBearing structure: free maintenance dual ball bearingsRotation direction: the wind from stents place eduction, facing the rotor counter-clockwiseThe wiring way: + red-black signal: blue (blue line, the alarm line speed, it is necessary to pay attention to). Line about 20 cm longThe biggest air volume: 26.8 m / hThe electric motor protection : overload protection, wrong level protection and stall lock current protectionMinimum wind pressure : 0.. 120 PaNoise index : 41.9 dB (A)Material qualitative material: glass fiber reinforced plastic, PBT shell, PA bladesFunction explain: electronic reversing the rotor dc fans, complete electronic directional control componentsColor: Blue as picture showSize: 75mm x 48mm/2.95"x1.89"(inch) (approx)Net Weight: 24gPackage includes:1 x LED display module

        ?

        Including the following resources:
        1. 8 key
        2. 8 LED common cathode
        3. 8 a digital tube common cathode
        Use TM1638 digital tube drive chip to drive common cathode LED digital tube
        How to connect:
        VCC GND 5V power supply, STB CLK DIO MCU I/O port
        This module for the chip TM1638, set the above three kinds of single chip microcomputer common peripheral circuit, the biggest characteristic is to simply take microcontroller three IO mouth can drive, scanning display and key scan don't need microcontroller intervention, only need to register to display data related to reading and writing or testing buttons, save MCU resources. Buy the module provides an example program.
        Wiring methods :
        VCC GND connected 5V supply, STB CLK DIO connected microcontroller IO port.
