  • No welding required for quick integration into projects

Ready-to-use I2S amplifier boards

This pack supplies five MAX98357 Class D modules that arrive without any soldering required. Each board accepts a single supply and drives a speaker directly from an I2S data stream. The modules suit hobbyists and developers adding audio output to microcontroller projects such as Arduino, ESP32 or Raspberry Pi platforms.

I2S interface limits and output capability

The digital input handles 35 clock configurations and 128 audio formats at sampling rates from 8 kHz to 96 kHz. Maximum output reaches 3.2 W into 4 Ω and 1.8 W into 8 Ω at 10 % THD. The high-immunity input tolerates jitter and suppresses electromagnetic interference, allowing longer speaker cables without extra filtering.

Check your host before ordering

Verify that your development board exposes an I2S peripheral and can provide the required clock signals. Confirm the speaker impedance matches either 4 Ω or 8 Ω for the rated power levels. Ensure your power supply delivers a clean voltage within the module's operating range, and plan for the mono output topology if your application needs stereo sound.

Questions about this item

Should I pick the 5-piece pack or a single module?

The listing supplies five identical MAX98357 I2S amplifier boards in one package, giving you spares for multiple projects or prototypes.

What does the 3.2 W rating mean when the board is connected to a 4 Ω speaker?

At 4 Ω and 10 % THD the module delivers 3.2 W of continuous output power from a single supply.

How does the I2S interface limit the audio formats I can use?

The I2S input accepts sampling rates from 8 kHz to 96 kHz and automatically configures to 128 digital audio formats with 35 clock options.
