Description
PWM Pulse Square Wave Signal Generator Full Function APWM Rectangular Wave Frequency Duty Cycle Adjustable DC 3.5-12V for MCU
The output duty cycle, frequency and amplitude of the module can be adjusted, and the upper and lower limits can be set; the default adjustment parameters (duty cycle/frequency/amplitude value) can be customized when the main interface is pressed by the button of "increase" or "decrease" ); The module has dual mode, normal mode and fine mode, the duty step in fine mode is 0.1%; with LCD liquid crystal display frequency, duty cycle and amplitude, very clear, with ON/OFF button, easy to use; There is a lock function to prevent misuse; the product can be used as a CNC power supply with a power of 3W, and all parameters are saved after power-off.
Product Parameters
