Key benefits Ready-to-use audio codec module that handles playback and recording so your microcontroller can offload decoding and encoding tasks. Simple SPI control and dedicated signal lines make integration into embedded projects fast and reliable. Built-in voltage regulation and single +5V power input reduce external parts and simplify power design. What it does (functions and performance) Plays multiple music formats with the module’s onboard decoder, enabling flexible audio playback without heavy host CPU load. Supports real-time OGG encoding for recording applications, allowing you to capture audio directly through the module. Onboard AMS-1117 LDO regulators provide 3.3V and 1.8V rails with up to 800 mA available, ensuring stable operation for the codec and peripheral circuits. Single +5V DC supply input with capacitor filtering for cleaner power and improved audio stability. Compatibility and integration Communicates via SPI for data and control; includes dedicated control signal lines for play/stop, record, and other commands to match typical microcontroller I/O schemes. Designed for use with standard 5V systems; the module’s internal regulators generate the required lower voltages. Minimal external components required thanks to built-in LDOs and onboard filtering. Practical attributes Function: Audio playback and real-time OGG recording. Interface: SPI data/command interface plus control signal lines. Power: Single +5V DC input; internal 3.3V and 1.8V AMS-1117 LDOs (800 mA max); capacitor filtering included. Performance: Offloads audio codec work from the host MCU, stable voltage rails for reliable audio processing. Typical applications Portable recording device or voice memo unit that needs onboard OGG encoding and simple MCU control. Embedded systems and IoT devices that require playback of audio prompts or music without tying up the main processor. Custom media players or alarm/notification modules in industrial or consumer products where compact, single-supply audio capability is required. Integration tips Feed the module with a clean +5V supply and ensure the recommended capacitor filtering is in place to minimize audio noise. Use the SPI bus for audio data transfer and the module’s control lines for play/record commands to simplify firmware design. Verify available current draw on your 5V source to accommodate the AMS-1117 regulators’ maximum current capability (up to 800 mA) and attached peripherals.
