Supporting I2S sampling rates from 8kHz to 96kHz and featuring automatic configuration for 35 clocks and 128 digital audio formats, it offers plug-and-play ease for Raspberry Pi and microcontroller projects. Its adjustable gain settings and no master clock requirement make it a versatile, reliable choice for professional-grade DIY audio applications. ## Description VCC: Positive power supply, DC 2.5V~5.5V GND: ground SD: Power off and channel selection. SD MODE is pulled low to place the device in shutdown. GAIN: Gain and channel selection. In TDM mode, the gain is fixed at 12dB DIN: digital input signal BCLK: Bit Clock Input LRC: Left/Right clock for 12S and LJ modes. Synchronous clock for TDM mode Review: Nice little I2C audio output. - Making my own voice assistant for Home Assistant and these seem to work fine. I was having a little problem with the quality of the audio and I put a better speaker and what a difference it made. I connected it up to an ESP32, added a microphone and status LED, uploaded code and was finished. Review: Meets expectations. - This is a cheap easy way to add and I2S amplifier to an ESP controller project. If you are willing to work through the many examples available on the Internet, it can be very rewarding to get I2S up and running. There is even and example that has a work around for I2S so that you can play short, simple music using an AVR Arduino Nano. ## Features - 1: Output power: 3.2W at 4Ω, THD is 10%; 8Ω is 1.8W, THD is 10% - 2: 12S sampling rate: 8Khz~96Khz - 3: Class D amplifier with optional gain: 3dB/6dB/9dB/12dB/15dB - 4: No master clock (MCLK) required - 5: Plug and Play: 35 different clocks and 128 digital audio formats can be automatically configured with only a single power supply ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0B4GK5R1R | | Best Sellers Rank | #63,738 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #10 in Audio Amplifiers | | Brand | Teyleten Robot | | Date First Available | June 18, 2022 | | Item Weight | 0.634 ounces | | Item dimensions L x W x H | 0.71 x 0.79 x 0.06 inches | | Item model number | Max98357 | | Manufacturer | Teyleten Robot | | Material | Copper, Silicon | | Maximum Supply Voltage | 5.5 Volts (DC) | | Minimum Supply Voltage | 2.5 Volts (DC) | | Mounting Type | Surface Mount | | Number of Channels | 3 | | Output Power | 3.2 Watts | | Product Dimensions | 0.71 x 0.79 x 0.06 inches | | Voltage | 5.5 Volts | ## Product Details - **Item dimensions L x W x H:** 0.71 x 0.79 x 0.06 inches - **Manufacturer:** Teyleten Robot - **Maximum Supply Voltage:** 5.5 Volts (DC) - **Minimum Supply Voltage:** 2.5 Volts (DC) - **Voltage:** 5.5 Volts ## Images ![Teyleten Robot Max98357 I2S 3W Class D Amplifier Breakout Interface Dac Decoder Module Filterless Audio Board for Raspberry Pi 5pcs - Image 1](https://m.media-amazon.com/images/I/81JUA-uKMTL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Nice little I2C audio output. *by A***. on April 18, 2025* Making my own voice assistant for Home Assistant and these seem to work fine.
