M5Stack DDS Unit (AD9833 Waveform Generator)

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

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!
