HS1891 DAC Module CJMCU-1334 UDA1334A I2S DAC Audio Stereo Decoder Module Board 3.3V - 5V
Feature:
This fully-featured UDA1334A I2S Stereo DAC breakout is a perfect match for any I2S-output audio interface.
3.3V - 5V logic levels and can process multiple different formats by setting two pins to high or low. The DAC will process data immediately, and give you a clear, analog, stereo line level output.
It will also work with MCLK-less I2S interfaces such as the Raspberry Pi (which it's ideal for) - a built in PLL will generate the proper clock from the incoming signal.
For inputs, you can use classic I2S (the default) or 16-bit, 20-bit or 24-bit left justified data. You can set it up to take an input system/master clock but we default-set it to just generate it for you, so you only need to connect Data In, Word Select (Left/Right Clock) and Bit Clock lines. Also there are a mute pin and a de-emphasis filter you can turn on.

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- DAC
- A digital-to-analogue converter turns numbers from the microcontroller into a real analogue voltage. It matters if you want to generate simple waveforms, audio-style signals, or variable control voltages rather than just on/off outputs.
- I2S
- I2S is a digital audio interface used to send sound data between chips, such as from a microcontroller to an audio amplifier or DAC. It matters if your project needs cleaner digital audio output than a basic buzzer or PWM signal can provide.
- line level
- Line level is an audio signal strength intended for inputs on mixers, amplifiers, powered speakers, or recording equipment. It is not the same as a speaker output, so you may still need an amplifier to drive passive speakers.
