M5Stack DDS Unit AD9833 Signal Generator

The DDS Unit by M5Stack is a signal generator. It uses the programmable waveform generator AD9833 and a STM32F0 microcontroller. Based on the I2C communication interface (address 0x31), the signal source can be easily controlled to generate various signals such as sine wave, triangle wave, square wave or sawtooth wave. The signal output amplitude can be adjusted between 0 to 0.6V.

Features:

• Frequency and phase digitally programmable
• Signal output amplitude selectable from 0 to 0.6V
• Sine wave/Triangle wave/Square wave/Sawtooth wave
• Output frequency range 0MHz to 1MHz
• 28bit frequency resolution
• 11bit phase resolution
