The core part of the ESP32 Audio Kit is ESP32- A1S module, it can work as a minimum independent system. Most audio interfaces are distributed on both sides of the development board for easy access, include a 3.5mm headphone jack, 3.5mm line-in jack, a pair of 2-pin headers for left/right speakers (up to 4Ω/3W output), and a couple of built-in microphones. The ESP32-Audio-Kit is outfitted with a dual-core Xtensa LX6 CPU (520Kb SRAM, 8Mb of PSRAM), micro SD slot (up to 64Gb of storage), and 802.11 b/g/n Wi-Fi + Bluetooth 4.2 LE.
