AD9833 Programmable Sine Square Wave DDS Signal Generator

The AD9833 Programmable Waveform Generator Module is a compact and versatile Direct Digital Synthesis (DDS) signal generator that produces sine, square, and triangle waveforms with programmable frequency and phase. Based on the Analog Devices AD9833 chip, it’s ideal for function generation, waveform simulation, audio testing, and as a signal source for embedded system development. It communicates via SPI interface, making it easy to integrate with microcontrollers like Arduino, STM32, Raspberry Pi, and more.

Features:
- Supports sine, square, and triangular wave output
- Programmable frequency and phase via SPI interface
- Output frequency: up to 12.5 MHz (sine), up to 3 MHz (square)
- Precision 10-bit DAC for high-quality waveform generation
