The PAM8610 2×10W Stereo Class D Audio Amplifier Module is a compact, high-efficiency dual-channel audio amplifier designed for small stereo speaker systems and embedded audio applications. Based on the PAM8610 Class D amplifier IC, the module can deliver up to 10W + 10W stereo output while maintaining low power loss and reduced heat generation compared with traditional linear amplifiers. The board features a standard 3.5mm stereo audio input, onboard volume control, heat dissipation, and over-current protection. Its compact PCB design makes it suitable for DIY speakers, portable audio equipment, IoT projects, and other space-limited applications.
Package Includes
- 1 × PAM8610 Class D Stereo Audio Amplifier Module
Features
- Based on the PAM8610 Class D audio amplifier IC.
- 10W + 10W stereo output, providing up to 20W total output power under suitable conditions.
- High-efficiency Class D amplification with low power loss and reduced heat generation.
- Designed for clean and high-quality stereo audio reproduction.
- Built-in audio noise-cancellation circuitry for improved sound quality.
- Supports 4Ω–8Ω speakers.
- Wide DC operating voltage range of 8V–12V.
- 3.5mm stereo audio input for convenient connection to standard audio sources.
- Integrated rotary potentiometer for convenient volume adjustment.
- Built-in heat sink for improved thermal management.
- Over-current protection helps protect the amplifier against excessive loads and short circuits.
- Compact PCB design suitable for space-constrained projects.
- Uses quality components for stable and reliable operation.
Principle of Operation
The PAM8610 module uses Class D switching amplification to convert the low-level stereo audio signal into a higher-power signal capable of driving external speakers. Unlike traditional Class A or Class AB amplifiers, the output transistors operate primarily as switches, significantly reducing power dissipation.
The left and right audio channels are amplified independently, allowing the module to drive two speakers as a stereo system. The amplified signals are connected to the corresponding left and right speaker outputs. The onboard potentiometer controls the input signal level and therefore provides convenient volume adjustment. The module also incorporates protection circuitry to help protect the amplifier against excessive current and short-circuit conditions.

Pinout
| Terminal / Interface | Function |
|---|---|
| VCC | Positive DC power input, 8V–12V |
| GND | Power supply ground |
| L+ | Left-channel speaker output positive |
| L− | Left-channel speaker output negative |
| R+ | Right-channel speaker output positive |
| R− | Right-channel speaker output negative |
| 3.5mm Audio Input | Stereo audio signal input |
Wiring
Connect a suitable DC 8V–12V power supply to the VCC and GND terminals. Connect the left and right speakers to their corresponding output terminals, then connect an audio source to the 3.5mm stereo input.
| Module Connection | Connection |
|---|---|
| VCC | DC 8V–12V positive supply |
| GND | DC power supply ground |
| L+ / L− | Left speaker, 4Ω–8Ω |
| R+ / R− | Right speaker, 4Ω–8Ω |
| 3.5mm Input | Phone, computer, MP3 player, microcontroller audio output, or other stereo audio source |
Important: The PAM8610 uses bridge-tied-load (BTL) speaker outputs. The speaker negative terminals should not be connected to the power supply ground or combined together. Each speaker must be connected between its corresponding positive and negative output terminals.
