Highlights:

Two independent PWM generators can set the frequency, duty cycle;
The wide frequency range, high accuracy;
Can serial communication.

First, the module description：

Frequency is divided into three ranges:

XXX (no decimal point): the smallest unit is 1Hz, the range 1Hz ~ 999Hz;
XX. X (decimal point in ten): The minimum unit is 0.1Khz; the range of 0.1KHz ~ 99.9KHz
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:

Working voltage: 5--30V, support micro USB 5.0V power supply;
Frequency range: 1Hz ~ 150KHz;
The frequency accuracy: ± 2%;
Output Current:
