New brand 3pcs NE555 Square Wave Signal Generator 1hz-500khz New NE555 Square wave signal generator 1hz-500khz This module scope: 1. as a square wave signal generator generates square wave signals, for experimental use. 2. for generating a driving stepping motor driver of the square wave signal. 3. generation of tunable pulse for MCU to use. 4. generation of tunable pulse, control circuit. Item Description: 1. the main chip: NE555; 2. he input voltage:5V-15VDC. 5V power supply, the output current can be controlled in 15MA;12V power supply, the output current can be controlled in 35MA; 3. the input current is greater than or equal to 100MA: 4. the amplitude of the output:4.2V V-PP to11.4V V-PP. ( according to different input voltage, output amplitude will be different ) 5. the maximum output current: = 15MA (5V power supply, V-PP > 50% ),35MA (12V power supply, V-PP greater than 50% ) advantages: 1. the output with LED indication, there is no output straightforward ( low LED lights, high LED, low frequency LEDflashing); 2. the output frequency range of grades are optional, so that the output frequency of a continuously adjustable; 3. LF :1Hz ~ 50Hz 4. MF :50Hz ~ 1kHz 5. MHF:1KHz ~ 10kHz 6. HF:10kHz ~ 500kHz 7. the output duty ratio can fine tune; 8. adjustable output frequency; period T = 0.7( RA+2RB ) C RA, RB for 0-10K adjustable; LF of C =0.001UF; MF of C =0.1UF; MHF of C = 1UF; HF of C =100UF so buyers can calculate the frequency of the waveform 3pcs in one package Payment:Paypal Shippment: We will ship in the 24 hours after we receive payment.
