About this product
The ESP32-A1S is a wireless audio module that combines an ESP32 dual-core SoC with an audio codec, flash memory, and PSRAM. It supports 2.4 GHz Wi-Fi, Bluetooth 4.2 BR/EDR and BLE, plus audio input and output connections for microphones and speakers. Module revisions use different codecs, so the exact version should be checked before software setup.
