Notice: The new tracking number for China Post Ordinary Small Packet Plus only can track it have been ship out of China, not more Tracking information ,even it arrived or not . Please do not freeloaders,if you can not accept without more tracking information .   Please choose China Post Air Mail if you want a full tracking info.   Tracking info of  China Post Ordinary Small Packet Plus can be check here : www.17track.net/en    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.   http://g003.a.acdn.com/kf/HTB1NxAcGXXXXXbuXpXXq6xXFXXXJ/220833420/HTB1NxAcGXXXXXbuXpXXq6xXFXXXJ.jpg?size=54225&0" src="http://g01.s.acdn.com/kf/HT1zxGHFN8gXXagOFbX6/220833420/HT1zxGHFN8gXXagOFbX6.jpg?size=3750&;

Good value, fast deliveryI ordered a pair of Asics netball shoes. They arrive quickly and were excellent value - cheaper than all other places I looked at online. I would recommend using Barrington Sports.

18 April 2012 <br/> Quality products and branding We ordered a batch of Fruit of the Loom Polo Shirts. Good quality shirts and embroidery on the front and printing on the back. All done to specification and arrived just-in-time. Nice touch of sending a picture by email with the shirts in the machine. Slight friction point was that when a colleague went on holiday and the urgency of the order appeared to be lost, but was quickly put on track by Justin the MD. The shirts arrived by pre-10:00 courier as we were about to leave for an event. Watch out, the female polo shirts are closely fitted and shorter than the male version. Would use again. Comment (?)
