New version of the DDS signal generator than m328 strong function 0.1hz~100khz + frequency meter module PP | Инструменты

DDS720 multiple signal generator
First, an overview:
DDS720 is a small variety of signal generator, the frequency can be measured 1HZ ~ 200KHZ. The highest can produce 100KHz sine wave signal, but also can produce triangular wave, Di Zengbo, descending wave, rectangular wave, the heart waves and a high frequency pulse output.
The module is easy to use, the input frequency data through the button operation.

Two, product application:
The signal generator;
- meter calibration;
The DC motor control;
The frequency meter;
