Item specifics


Brand Name: module

Model Number: Ne555 Ne555 module: Stepper Motor Driver module
Place of Origin: China (Mainland)
First, this module Scope:  1 is used as a square wave signal generator generates a square wave signal for experimental development to use.  2 is used to generate drive stepper motor drives a square wave signal.  3 adjustable pulse generation for MCU to use.  4 generates an adjustable pulse, the control-related circuit.  Second, a brief description:  1, Size: 3.1CM * 2.2CM  1, the main chip: NE555;  2, the input voltage: 5V-15VDC. 5V supply, the output current can be about 15MA; when 12V power supply, the output current can be about 35MA;    3, the input current: ≥100MA  4, the output amptude:. 4.2V V-PP to 11.4V V-PP (different depending on the input voltage, the output amptude will be different)  5, the maximum output current: ≥15MA (5V supply, V-PP greater than 50%), ≥35MA (12V power supply, V-PP greater than 50%)      Three Advantages:  1, the output with LED indication, there is no output straightforward (low level LED quantity, high LED off, LED bnks when the frequency is low);  2, grade selectable output frequency range, the output frequency is more continuously adjustable;  LF file: 1Hz ~ 50Hz  IF file: 50Hz ~ 1kHz  High frequency gear: 1KHz ~ 10kHz  High frequency profile: 10kHz ~ 200kHz    3, the output duty cycle can be fine-tuning, duty cycle and frequency are not separately adjustable, adjusting the duty cycle will change the frequency;        4, the output frequency is adjustable;  Cycle T = 0.7 (RA + 2RB) C    RA, RB for 0-10K adjustable;    At low frequencies stalls C = 0.001UF;  IF stalls when C = 0.1UF;  High-frequency gear C = 1UF;  When high-frequency gear C = 100UF, therefore frequency waveform buyers can own calculations.

21 January 2011 <br/>Service second to none and product excellent I have used TShirt Studio for a few years now. Buying personalised mugs for friends and family. I have just recieved the three mugs I ordered on line and they are fab. Great quality and extremely well packaged so that they got to me in one piece! Ordered on Sunday night and recieved them on the Wednesday - fantastic. I continue to recomend TShirt Studio as I know the service is second to none and the product is excellent
