Recommended Amplifier: PAM8403 2 × 3W Digital Audio Amplifier
The PAM8403 is a practical choice for small Arduino, ESP32, and Raspberry Pi audio projects.
- Operates from a 5V DC supply.
- Supports 4Ω and 8Ω speakers.
- Provides stereo audio output.
- Compact and suitable for embedded projects.
- Can drive one 8Ω speaker from a single amplifier channel.
For higher output levels, use an amplifier capable of delivering approximately 5W into 8Ω without exceeding the speaker's rated power.
Connection Example – PAM8403 Amplifier
- Connect a regulated 5V supply to the amplifier's power input.
- Connect the audio source to the amplifier's audio input.
- Connect the speaker to one amplifier channel's positive and negative speaker outputs.
- Start at a low volume and increase gradually.
Important: Do not connect either speaker terminal of a bridge-tied amplifier output directly to ground.
Applications
- Arduino and ESP32 Audio Projects
- Raspberry Pi Sound Systems
- DIY Bluetooth Speakers
- Robotics Voice and Sound Effects
- Electronic Alarm Systems
- Voice Playback Modules
- Educational Audio Projects
- Small Portable Audio Devices
Important Notes
- The speaker is passive and does not include a built-in amplifier.
- Use an amplifier compatible with an 8Ω speaker.
- Do not exceed the 5W rated power.
- Avoid excessive volume or distorted audio that may damage the speaker.
- Do not connect the speaker directly to microcontroller GPIO pins.
- Speaker dimensions and frequency response should be verified before enclosure design.
