Frequency PWM Signal Generator Module Adjustable
XY-KPWM PWM signal generator is a low-cost standard panel-mounted adjustable PWM signal generator meter with LCD display. Its output frequency range is 1Hz to 150KHz, duty cycle is 0%-100%. duty cycle and frequency signal are adjustable through precision encoders’ knob. It supports UART TTL communication. It is widely used as a signal source or excitation source for testing.
