What You Can Build With This
- Precision function generator for electronics lab
- Audio tone generator for musical instruments
- RF test signal source for receiver testing
- Variable frequency drive for motor control
Compatibility
Works with 3.3V and 5V microcontrollers like Arduino Uno, Nano, ESP32, STM32, and Raspberry Pi Pico. The SPI interface uses standard digital pins. Many libraries available for easy frequency and waveform control. Pair with an amplifier for higher output levels.
Wiring Notes
Connect VCC to 3.3V (5V may damage), GND to ground, and SPI pins SDATA, SCLK, FSYNC to microcontroller digital pins. Use 10kΩ pull-up resistors on data lines if driving long wires. Keep signal traces short to minimize noise.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, the AD9833 module works with Arduino using the SPI library. There are several open-source libraries that simplify generating waveforms.
Can I get a 0-5V output from this module?
The module outputs around 0.65V peak-to-peak. You can use an op-amp amplifier circuit to scale the output to 0-5V or higher.
Does this module include a crystal oscillator?
Yes, most AD9833 modules include a 25 MHz crystal oscillator for the reference clock, enabling precise frequency generation.
