Description

The M5Stack DDS Unit is a signal source unit that uses an AD9833 programmable waveform generator and an STM32F0 microcontroller. The Unit can easily control the signal source to output multiple waveforms (sine wave, triangle wave, square wave output, sawtooth wave, signal output amplitude 0-0.6V) and adjust the frequency and phase. This DDS Unit is based on an I2C communication interface (addr:0x31). It supports deep sleep mode, reducing the power consumption in the idle state. It’s perfect for applications such as electronic circuit prototype design of various test instruments as a signal source.
