Compact and Efficient Audio Recording
This module features a built-in recording chip that accommodates up to 35 seconds of high-quality audio storage. When paired with an external SPI flash chip, such as a 32Mbit flash, recording capacity extends to approximately 350 seconds, giving flexibility for longer applications.
The compact 31.6 x 31.6 x 11.5mm design makes it easy to integrate into various projects and devices requiring voice or sound recording capabilities.
User-friendly Recording and Playback Controls
A dedicated recording button enables continuous recording by pressing and holding; releasing the button stops recording immediately. LED indicators clearly show recording status by flashing and playback status by remaining steady.
Playback modes can be customized via two dip switches, allowing selection among multiple playback options, enhancing functionality and user control.
Low Power Consumption and Convenient Power Input
The module supports a DC power input range from 2 to 5.2 volts, accommodating a variety of power sources. For operation below 3.3 volts, the 3.3V and VCC pins should be shorted for proper functionality.
Standby current is minimal at just 2 microamps, making this module ideal for battery-powered or low-power applications where energy efficiency is critical.
Built-in Speaker and Simple Integration
Includes an 8-ohm, 0.5-watt speaker, providing ready output capabilities without need for additional audio components.
The module’s size and interface are designed for straightforward integration into electrical DIY projects, enhancing versatility across applications.
