Gravity I2C Voice Recorder Module EDU
DFRobot's all-in-one I2C voice recorder & playback module for Arduino, micro:bit. Features recording, synthesis & 10x100s storage.
The Gravity I2C Voice Recorder Module EDU from DFRobot is an all-in-one voice interaction solution, ingeniously integrating recording and playback functions into a single, compact module. It offers the convenience of one-button recording and is also programmable via its Gravity I2C interface for more sophisticated control from a microcontroller.
A standout feature is its number synthesis function, allowing for the direct audio playback of numerical data such as temperature, humidity, voltage, or time with minimal programming effort. The module supports audio output through either a 3.5mm headphone jack or a PH2.0 speaker port and includes a built-in amplifier for plug-and-play simplicity.
Designed for makers and educators, it boasts broad compatibility with popular development boards including Arduino AVR, micro:bit, mPython, and Firebeetle-ESP32. It offers substantial storage capacity for audio projects, capable of holding up to ten separate audio segments, each with a maximum length of one hundred seconds.
The module operates across a flexible voltage range from 3.3 to 5V, making it suitable for a wide array of electronics projects. Its compact PCB features four M3 mounting holes for easy and secure installation into your prototype or finished project.
This versatile tool is perfect for creating interactive exhibits, educational aids, smart home notifications, or any project requiring clear, pre-recorded or dynamically generated audio feedback. Its educational (EDU) focus ensures it is an accessible and powerful component for learning about digital audio and microcontroller interfacing.
