The ESP32 Audio Kit is based on Ai-Thinker’s ESP32-A1S with most of the interfaces located at the edge of the development board for easy access. As far as hardware goes, 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. Audio ports are many and include 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.

Expansion options include headers for I2C, UART, SPI, PWM, and an unpopulated header for JTAG with micro USB port for UART access. It also features six user buttons, as well as 5V/2A via micro USB, and support for 3.7V Li-ion battery via 2-pin header for power options.
