Digital Speaker Module from DFRobot

This Digital Speaker Module removes the need for an amplifier, allowing for easy audio integration for your next project!

If you love to tinker with Electronics, but often feel like your projects are simply incomplete without audio, then this compact little Digital Speaker Module from DFRobot is the perfect solution!

Known affectionately in many Maker communities as the DFSpeaker, these fantastic little Audio Modules are more than just capable of playing sound, and actually have an integrated 8002 Speaker Amplifier IC built directly into the units. This means you don’t need any other equipment or converters to turn the data signals you send into audio packets for the speaker, making integration as easy as possible – Just like it should be for Arduino projects.

TYPICAL APPLICATIONS FOR THESE DIGITAL SPEAKER MODULES FROM DFROBOT:
The DFRobot Digital Speaker Module is one of the simplest Audio Modules available to Makers, with a built-in amplifier to handle all of the complicated signal conversions and audio translations that we as Electronics tinkerers shouldn’t NEED to know. This allows us Makers (and sound “non-specialists”) to benefit from the countless hours of hard work that sound engineers and specialists in the audio field.

And just to sweeten this already awesome deal, this Digital Speaker Module has been tested to work perfectly on expansion boards like the Arduino I/O Expansion Shield, allowing you to integrate audio into almost any Arduino project with absolute ease.
