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. ## 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.nz/products/508824943-esp32-a1s-audio-development-board-module-wifi-bluetooth-module](https://www.desertcart.nz/products/508824943-esp32-a1s-audio-development-board-module-wifi-bluetooth-module) --- *Product available on Desertcart New Zealand* *Store origin: NZ* *Last updated: 2026-08-12*
