SELAMAT DATANG 102306651/12024809342 HW-753 1Hz-150KHz Boost Sigl Generator PWM Board Module Pulse Frequency Duty Cycle Adjustable Module Specification: Product size: 52*32*6mm Product weight: 16g Packing size: 100*100*30mm Package weight: 16g Module description: PWM output, the frequency and duty cycle can be set separately; the frequency is divided into four ranges, Automatic switching: 1.XXX (no decimal point): the smallest unit is 1Hz, and the value range is 1Hz-999Hz; 2. The minimum unit of X.XX (the decimal point is in the hundreds) is 0.01KHz, and the value range is 1.00KHz-9.99KHz; 3.XX.X (the decimal point is in the tens place): the smallest unit is 0.1KHz; the value range is 10.0KHz-99.9KHz; 4. X.X.X (the decimal point is in the tens and hundreds): the smallest unit is 1KHz; the value range is 100KHz-150KHz; e.g. Frequency display: 100 means PWM output pulse of 100Hz; 1.01 means PWM output pulse of 1.01K; 54.1 means PWM output pulse of 54.1KHz; 1.2.4 means PWM output pulse of 124KHz; Duty cycle value range: 0-100%; all setting parameters are saved after power-off. Parameter settings: The module has 4 independent buttons to set the frequency and duty cycle. It supports short press (increase or decrease by one unit) and long press ( increase or decrease). It is very simple. The parameters are automatically saved after setting, even if the power is off, nor is it lost. Scope of application: 1. Used as a squaresigl generator to generate squaresigls for experimental development and use; 2. Used to generate a squaresigl for controlling the motor driver; 3. Generate adjustable pulses for MCU use; 4. Generate adjustable pulses and control related circuits (applicat
