8-Bit LED 8-Bit Digital Tube 8 KeyS TM1638 Display module for AVR for Arduino ARM

Description: Weight:28 gColor: as picture showSize:75mmx48mm/2.95"x1.89"(inch) (approx)The rated voltage: DC12VVoltage range: DC7.0 V-13.6 VThe input power: 0.24 AThe rated speed: 9500 R.P.MTemperature range:-10.. 70 ¡ã CTxpect life: 25 ¡ã C 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 componentsIncluding the following resources:1. 8 key2. 8 LED common cathode3. 8 a digital tube common cathodeUse TM1638 digital tube drive chip to drive common cathode LED digital tubeHow to connect:VCC GND 5V power supply, STB CLK DIO MCU I/O portThis 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. Package Included: 1 x 8-Bit LED Tube?(Without dupont cable)
