50Hz-6KHz TP354 NE555 Module Square Wave Pulse

50Hz-6KHz TP354 NE555 Module Square Wave Pulse Generator Oscillator Output Signal Source Frequency Adjustable 200mA DC 5-15V

Introduction:

1.Power Voltage:DC 5-15V;no load operating current 2.5MA(5V);no load operating current 6.5MA(12V)

2.Output Driving Current:200MA MAX

3.Applications:as signal source

4.Size:13*10*8mm(not include pin);pin space 2.54mm

Functions:

1.Ar adding power,output port will output square signal,and amplitude is equal to power voltage

2.Output duty cycle cannot adjusted,and output siganl duty cycle is basically stable during adjusting freuquency (58%)

3.Frequency can be adjusted by multi-coil potenitometer:50Hz~6kHz

4.V1 port is uesd to control module start/stop vibrating

Using Method:

1.Connect with power,and then it can operate

2.When V1 port is high level or hanging,module start vibrating output signal;V1 port connects with ground,module will stop vibrating,and output is low level

3.When using,0.1uf power filter capacitor can be connected with power to make sure stable operation

4.Clockwise adjust potentiometer,frequency will increase;anti-clockwise adjust potentiometer,frequency will decrease

Pin Definition:

1.VCC:power

2.Vo:signal output port

3.Vi:start /stop vibrating control port

4.GND:ground
