Signal Generator PWM Pulse Frequency Duty Cycle Adjustable Module 7 segment BCD Display 1Hz-150Khz 3.3V-30V

Features:

• Brand new and high quality.
• Suitable for serial communication.
• Wide frequency range, high accuracy.
• Two independent PWM generators can set the frequency and duty cycle.

Module Parameters:

• Working voltage: 5–30V, support micro USB 5.0V power supply.
• Frequency range: 1Hz ~ 150KHz.
• The frequency accuracy: ± 2%.
• Output current: <30mA.
• Output amplitude: Default 5Vp-p (settable).
• Operating temperature range: -30 ~ + 70 ℃.
• Product size: 4.3×2.9×0.9cm – 1.69×1.14×0.35in

Parameter Settings:

• Module has three buttons: [Set], [Up], [Down].
• Press [Set] key to switch the display of four parameters (FR1: PWM1 frequency; dU1: PWM1 duty cycle; FR2: frequency of PWM2; dU2: PWM2 duty cycle), before the handover parameters, there will be corresponding parameter name flashing.
• Press [Up], [Down] keys to modify the current parameter value (long press can quickly add or subtract fast).
• Two PWM each have three preset frequency, and in the frequency display interface, long press [SET] key to switch between three types of frequencies, three kinds of frequency duty cycle is the same. (XXX: range 1Hz ~ 999Hz; XX.X: range 0.1Khz ~ 99.9Khz; X.X.X .: range 1Khz ~ 150Khz).

Applicable Scopes:

• To generate a square wave signal for experimental development as a square wave signal generator.
• To generate a square wave signal for stepping motor driver.
• To generate adjustable pulse generation for chip use.
• To generate variable pulse signal for controlling related circuit (PWM dimming, speed).
