Module pulse generator with adjustable duty cycle based on the integrated NE555 used as a square wave generator, as a driver for stepper motor or for experimental use.
As generator originates a square wave signal.
As a unit for generating a control signal square wave by stepper motor
As adjustable pulse generator for use with the MCU.
Control output with LED
Wide frequency range, the output frequency is programmable via links.
Low Frequency: 1Hz ~ 50Hz
Medium frequency: 50Hz ~ 1kHz
High frequency: 1kHz ~ 10kHz
High frequency: 10kHz ~ 200kHz
3, the output frequency is adjustable;
Cycle T = 0.7 (2 RA RB) C
VR1, VR2 0-10K is adjustable;
At low frequencies the capacitor C = 1UF;
Mids C = 0.1UF;
High frequency C = 0.001UF;
