Review: Good Dev Board, with audio CODEC - Great board, but note that the two MICs and the Line-In is tied together. A known issue, that would have been good to know. Review: Works for me - The documentation one finds is somewhat scarce. The idea to couple some of the few externally available pins with LEDs and others with on board buttons is most disturbing. One can only use most pins by cutting lines in the board. But that aside it works perfectly fine for me for a couple of months now. I play mp3 from the SD card and web streams to speaker and (or) headphones. I sort of connected an RFID reader to start playing the files/folders from SD... BUT due to the lack of pins I put a microbit between this board and the RFID reader. So: if you are prepared to go through a considerable pile of hazzle and disappointment you get a very cool device at a fair price. ## 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, support TF card, 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 ### ⭐⭐⭐⭐⭐ Good Dev Board, with audio CODEC *by R***E on 2 May 2026* Great board, but note that the two MICs and the Line-In is tied together.

No documented pin routing to the HAL and Codec, no documented Codec, and no working software support library. This board will not work with the ESP-ADF and ESP-IDF libraries out of the box. ## 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.ni/products/517305228-esp32-audio-kit-audio-development-board-esp32-a1s-audio-development](https://www.desertcart.ni/products/517305228-esp32-audio-kit-audio-development-board-esp32-a1s-audio-development) --- *Product available on Desertcart Nicaragua* *Store origin: NI* *Last updated: 2026-07-08*
