PWM pulse frequency duty cycle adjustable module square wave rectangular wave signal generator
Module Highlights:
1.LCD display frequency and duty cycle, very clear, PWM output can be set to the frequency and duty cycle;
2. Wide frequency range, high precision;
3. Serial communication, TTL level
First, the module description
PWM output, you can set the frequency, duty cycle;
Frequency is divided into four ranges, automatic switching:
1. XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz;
2. X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz;
3. XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz
4. X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz
frequency display: 100 indicates PWM output 100Hz pulse;
1.01 indicates PWM output 1.01K pulse;
54.1 indicates that the PWM output has a pulse of 54.1 kHz;
1.2.4 indicates that the PWM output is 124 kHz pulse;
Duty cycle range: 0 ~ 100%;
All set parameters, power-down automatically saved.
Second, the parameter settings
The module has four independent keys, used to set the frequency and duty cycle, support touch (increase or decrease a unit) and long press (fast increase or decrease), set the parameters automatically save, power down Not lost.
Third, the module parameters:
1. Working voltage: 3.3 ~ 30V;
2. Frequency range: 1Hz ~ 150KHz;
3. Frequency accuracy: the accuracy in each range is about 2%;
4. Signal load capacity: the output current can be about 5 ~ 30ma;
5. Output amplitude: PWM amplitude equal to the supply voltage;
6. Ambient temperature: -20 ~ +70 °.
Fourth, the scope of application:
1. Used as a square wave signal generator, generate square wave signal for experimental development and use;
2. Used to generate a square wave signal that controls the motor driver;
3. generate adjustable pulse for MCU use;
4. generate adjustable pulse, control the relevant circuit (PWM dimming speed and other applications).
5, serial control (single-chip TTL level communication)
Communication standard:
9600 bps Data bits: 8
Stop bit: 1
Check digit: none
Flow control: none
1, set the frequency of the PWM
"F101": Set the frequency to 101 HZ (001 to 999)
"F1.05": set the frequency of 1.05 KHZ (1.00 ~ 9.99)
"F10.5": Set the frequency to 10.5KHZ (10.0 ~ 99.9)
"F1.0.5": set the frequency of 105KHZ (1.0.0 ~ 1.5.0)
2, set the PWM duty cycle
"DXXX": set the PWM duty cycle to XXX; (001 ~ 100)
Such as D050, set the PWM duty cycle is 50%
3, read the set parameters
Send a "read" string to read the set parameters.
Set successfully return: DOWN;
Setup failed to return: FALL.
Purchasing & Delivery
Before you make your purchase, it’s helpful to know the measurements of the area you plan to place the furniture. You should also measure any doorways and hallways through which the furniture will pass to get to its final destination.Picking up at the store
Shopify Shop requires that all products are properly inspected BEFORE you take it home to insure there are no surprises. Our team is happy to open all packages and will assist in the inspection process. We will then reseal packages for safe transport. We encourage all customers to bring furniture pads or blankets to protect the items during transport as well as rope or tie downs. Shopify Shop will not be responsible for damage that occurs after leaving the store or during transit. It is the purchaser’s responsibility to make sure the correct items are picked up and in good condition.Delivery
Customers are able to pick the next available delivery day that best fits their schedule. However, to route stops as efficiently as possible, Shopify Shop will provide the time frame. Customers will not be able to choose a time. You will be notified in advance of your scheduled time frame. Please make sure that a responsible adult (18 years or older) will be home at that time.In preparation for your delivery, please remove existing furniture, pictures, mirrors, accessories, etc. to prevent damages. Also insure that the area where you would like your furniture placed is clear of any old furniture and any other items that may obstruct the passageway of the delivery team. Shopify Shop will deliver, assemble, and set-up your new furniture purchase and remove all packing materials from your home. Our delivery crews are not permitted to move your existing furniture or other household items. Delivery personnel will attempt to deliver the purchased items in a safe and controlled manner but will not attempt to place furniture if they feel it will result in damage to the product or your home. Delivery personnel are unable to remove doors, hoist furniture or carry furniture up more than 3 flights of stairs. An elevator must be available for deliveries to the 4th floor and above.
