Module Description:
AD9833 is a low-power, programmable waveform generator that can generate sine wave, angular wave and square wave output.

Various types of detection, actuation, and time domain reflectometry (TDR) applications require waveform generators. The output frequency and phase can be programmed through software, which is easy to adjust. No external components are required. The frequency register is 28 bits; the clock rate is 25MHz, which can achieve a resolution of 0.1H. Similarly, when the clock rate is 1MHz, AD9833 can achieve a resolution of 0.004Hz.

Precautions:
(1) The module is a low-power module, and power supply does not exceed 5.5V.
(2) The module is a high-precision device. In order to avoid unnecessary interference, it is recommended to use a linear power supply.
(3) It is recommended to use SMA to BNC cable for input signal, and directly observe the effect with an oscilloscope. Poor contact or poor quality cables may cause signal attenuation or excessive noise.
(4) The code is only used for main control board, no MCU tutorial is provided, and additional functions need to be developed by yourself.
(5) If you need to simply test the function of the module, it is recommended to use it with our control board. Power the DDS module first, and then power the control board to generate waveform, long press the middle button to switch functions.
