Key Features
NS8002 MONO SPEAKER MODULE: Combines an NS8002 Class-AB audio amplifier circuit with a built-in 29.3mm speaker for compatible Arduino boards, microcontrollers and electronic building-block projects.
SUPPLIER-SPECIFIED 2–5V INPUT: Designed to operate from a specified 2–5V supply. Confirm the board markings, polarity and controller voltage before connection; performance at the lowest supply voltage may depend on the installed components.
0.5W 8Ω BUILT-IN SPEAKER: The integrated mono speaker is rated at 0.5W and 8Ω. It is suitable for controller-generated tones, alarms, prompts, notification sounds and other simple audio-output applications.
MANUAL VOLUME CONTROL: An onboard potentiometer adjusts the playback level. On this module, turning the control counterclockwise increases volume; begin at a low setting and increase it gradually during testing.
COMPACT PH-INTERFACE BOARD: Measures approximately 36 × 45mm and includes a PH-style signal interface and approximately 3mm mounting holes. It is not an MP3 decoder, music-storage device or TF-card playback module.

Description
Elecbee NS8002 Big Speaker Audio Amplifier Module
The Elecbee NS8002 Big Speaker Module combines a mono Class-AB amplifier circuit, integrated speaker and manual volume control on one compact board. It is designed for compatible Arduino boards, microcontrollers and electronic building-block systems requiring simple sound output.
The board amplifies a compatible signal generated by an external controller. It does not contain music memory, an MP3 decoder or a TF-card interface and cannot independently play stored audio files.
Technical Specifications
Product Type: Mono speaker audio amplifier module
Amplifier IC: NS8002
Amplifier Class: Class AB
Supplier-Specified Module Voltage: 2–5V
Signal Port: Supplier-listed digital/signal port
Connector: PH-style interface; pin count and pitch not specified
Built-In Speaker Diameter: Approximately 29.3mm
Built-In Speaker Rating: 0.5W, 8Ω
Audio Channels: 1, mono
Volume Adjustment: Onboard potentiometer
Adjustment Direction: Counterclockwise rotation increases volume
Construction: Soldered and surface-mount components
Board Dimensions: Approximately 36 × 45mm
Mounting Hole Diameter: Approximately 3mm
Compatible Platforms: Compatible Arduino boards and microcontrollers
Voltage Note: The complete module is supplier-specified for 2–5V operation. Published NS8002 IC information commonly specifies operation from approximately 3V, so verify acceptable performance if the module will be powered below 3V.
Signal Input and Sound Generation
The module requires an externally generated signal from a compatible Arduino board, MCU or signal source. The connected controller determines the tone, pattern, duration and other sound characteristics.
Typical uses include beeps, alarms, notification tones and simple programmed sound effects. More complex music or voice playback requires an appropriate external audio-generation or decoding circuit.
Interface Note: “Digital port” is the supplier’s module-interface description and does not establish a standard digital-audio protocol. Verify the power, ground and signal pin positions before connection.
Manual Volume Adjustment
The onboard potentiometer provides direct manual control of the playback level. On this particular board, counterclockwise rotation increases the volume.
Begin testing at a low volume and adjust gradually. Excessive input amplitude or sustained overdrive may cause audible distortion and place unnecessary stress on the 0.5W speaker.
Applications and Limitations
The module is suitable for compatible Arduino learning systems, microcontroller development projects, electronic alarms, notification devices, interactive displays, electronic toys and other embedded applications requiring compact mono sound output.
Not an MP3 Player: The module cannot decode MP3 files by itself.
No Audio Storage: It does not contain onboard memory for music or voice files.
No TF-Card Support: A memory card cannot be inserted into this module.
External Signal Required: Playback requires a compatible signal generated by an external controller or audio source.
Verify the Interface: Confirm supply voltage, polarity and PH-interface pinout before applying power.
