When synched together via LMS, audio is synched in real tone between all speakers these are attached to, providing high quality whole-house audio for a fraction of the cost of commercial systems. Very happy with these, especially with 3D printed cases available online from the usual places. Review: Had some issues but figured them out finally - This board is pretty unique. No support really and information is scattered around everywhere. I can give a tip though. I was able to use esp-adf with a github repository I found. Search for esp-adf-component-ai-thinker-esp32-a1s on github and you'll be able to go forward with the examples. ## Features - ★Parameters： ✮Development board model： ESP32-Audio-Kit_V2.2 ✮Package： DIP-16 ✮Antenna form： Onboard PCB Antenna ✮Spectrum range：2400 - 2483.5MHz ✮Operating temperature：-40 °C ~ 85 °C ✮Storage environment ：-40 °C~125 °C, 1A ✮Support interface： UART/GPIO/ADC/PWM/I2C/ ✮Serial port speed： Support 110~4608000 bps, default 115200 bps ✮Bluetooth： Bluetooth 4.2 BR/EDR and BLE standards ✮Safety： WEP/WPA-PSK/WPA2-PSK - ★Independent research and development: ESP32-Audio-Kit is a small audio development board based on the ESP32-A1S module, most audio peripherals are distributed on both sides of the development board, headphone output, two microphone inputs, and two calls The output is convenient for developers to develop quickly. - ★Music playback: ESP32-Audio-Kit supports music player or recorder, supports audio formats, such as MP3, AAC, FLAC, WAV, OGG, OPUS, AMR, TS, EQ.

I’m most interested in capturing voice and streaming over http to do voice rec** A: There are a few. Marcel something on YouTube has a few videos explaining this particular module. The different audio codecs confused me a little at first. This module uses the Es8388 instead of AC101. There need to be more videos explaining the difference between the two codecs. Maybe an idea for a video particularly on the es8388 codec and setup. I tried using the Expressif Tools but my Chinese isn’t the greatest. These boards make great audio workstations with a little Programing experience anyone can get these up and running. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Whole house synched audio on a budget *by P***N on July 14, 2026* I have 5 of these flashed with squeezebox in my home. When synched together via LMS, audio is synched in real tone between all speakers these are attached to, providing high quality whole-house audio for a fraction of the cost of commercial systems. Very happy with these, especially with 3D printed cases available online from the usual places. ### ⭐⭐⭐⭐ Had some issues but figured them out finally *by A***R on December 4, 2024* This board is pretty unique. No support really and information is scattered around everywhere. I can give a tip though. I was able to use esp-adf with a github repository I found. Search for esp-adf-component-ai-thinker-esp32-a1s on github and you'll be able to go forward with the examples. ### ⭐⭐⭐ Need more documentation *by A***R on July 13, 2026* Used this as the base for a Bluetooth speaker project. Poor documentation and no support with this. However. Once it works. It works great, Bluetooth connection sounds decent. No feed back. And plenty of expandability. ## Frequently Bought Together - EC Buying ESP32-Audio-Kit Audio Development Board, ESP32-A1S Audio Development Board Module, WiFi+Bluetooth Module, ESP32 Serial Port to WiFi ESP32 Audio Kit/ESP32 Ethernet - Gikfun 2" 4Ohm 3W Full Range Audio Speaker Stereo Woofer Loudspeaker for Arduino (Pack of 2pcs) EK1725 - Teyleten Robot Max98357 I2S 3W Class D Amplifier Breakout Interface Dac Decoder Module Filterless Audio Board for Raspberry Pi Esp32 5pcs --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.kr/products/508824943-ec-buying-esp32-audio-kit-audio-development-board-esp32-a1s](https://www.desertcart.kr/products/508824943-ec-buying-esp32-audio-kit-audio-development-board-esp32-a1s) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-08-21*
