DDS Unit (AD9833 Waveform Generator)

by M5Stack

Make some waves with this handy Direct Digital Synthesis signal source unit, which includes an AD9833 programmable waveform generator and a STM32F0 micro controller.

Communicating via I2C (addr:0x31), it can output multiple waveforms (sine wave, triangle wave, square wave output, sawtooth wave, signal output amplitude 0-0.6V) with adjustable frequency and phase.

It also supports deep sleep mode, which can reduce power consumption when idle. Perfect for generating waves for feeding into a synth or even for creating a whole new electronic musical instrument!

Features

  • Digital programmable frequency and phase
  • Signal output amplitude 0-0.6V
