How to order

1. Two independent PWM generators can set the frequency, duty cycle;

2. The wide frequency range, high accuracy;

3. Can serial communication.

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.


Second, the 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 ℃.
