Description Description&Previewshipping&policy Micro usb dc 2ch pwm signal generator duty cycle pulse frequency moY od DESCRIPTION: Features: 1. Brand new and high quality. 2. Suitable for serial communication. 3. Wide frequency range, high accuracy. 4. Two independent PWM generators can set the frequency and duty cycle. Module Parameters: 1. Working voltage: 5--30V, support micro USB 5.0V power supply. 2. Frequency range: 1Hz ~ 150KHz. 3. The frequency accuracy: ± 2%. 4. Output current: <30mA. 5. Output amplitude: Default 5Vp-p (settable). 6. Operating temperature range: -30 ~ + 70 °. 7. Product size: 4.3x2.9x0.9cm - 1.69x1.14x0.35in Parameter Settings: 1. Module has three buttons: [Set], [Up], [Down]. 2. 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. 3. Press [Up], [Down] keys to modify the current parameter value (long press can quickly add or subtract fast). 4. 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,). First, the module description: Frequency is divided into three ranges: 1.XXX (no decimal point): the smallest unit is 1Hz, the range 1Hz ~ 999Hz; 2.XX.X (decimal point in ten): The minimum unit is 0.1Khz; the range of 0.1KHz ~ 99.9KHz 3.X.X.X. (there are three decimal point): the smallest unit is 1Khz; the range 1KHz ~ 150KHz Frequency display example: "100" indicates that the PWM output pulse of 100Hz; "54.1" indicates that the PWM output pulse of 54.1KHz; "1.2.4." Indicates that the PWM pulse output 124KHz Duty Cycle in the range: 0 to 100; Three frequencies duty cycle is the same, all the parameters non-volatile. Applicable Scopes: 1. To generate a square wave signal for experimental development as a square wave signal generator. 2. To generate a square wave signal for stepping motor driver. 3. To generate adjustable pulse generation for chip use. 4. To generate variable pulse signal for controlling related circuit (PWM dimming, speed). Fourth, the scope: 1.As square wave signal generator which generates a square wave signal; 2.To provide a signal to the stepping motor driver; 3.Adjustable pulse generation for chip use; 4.Produce variable pulse signal, the control-related circuit (PWM dimming, speed). Fifth, the serial control Baud rate: 9600 bps Data bits: 8 Stop bits: 1 Parity bit: none Flow control: none 1, set the PWM frequency "S1FXXXT": setting PWM1 frequency of XXX HZ (001 ~ 999) "S1FXX.XT": set the frequency of PWM1 XX.X KHZ (00.1 ~ 99.9) "S1F: X.X.X.T": setting PWM1 frequency of XXX KHZ (0.0.1 ~ 1.5.0..) 'S1': PWM1 'S2': PWM2 'F': Frequency 'D': Duty Cycle 'T' is the end flag Set the PWM duty cycle " Preview: Thank you for your purchase Problems? You can follow below process to chontact us.
