ESP32-A1S Specification
ESP32-A1S is a Wi-Fi+BT voice module developed by Shenzhen Anxinke Technology Co.,Ltd.The module's core processor chip ESP32 integrates 2.4 GHz Wi-Fi and Bluetooth dual mode,and the module also integrates ES8388 voice codec chip, PSRAM and Flash chip.It can be widely used in offline voice products and various loT
hardware terminal occasions.
ESP32 chip has industry-leading low-power performance and radio frequency performance,supports Wi-Fi IEEE802.11 b/g/n protocol and Bluetooth V4.2 complete standard,including traditional Bluetooth(BR/EDR)and low energy Bluetooth(BLE)
The chip is equipped with an Xtensa® 32-bit LX6 dual-core processor with a computing power of up to 600 MIPS and a working frequency of up to 240 MHz.Support secondary development without using other microcontrollers or processors.The chip has built-in 520 KB SRAM,448 KB ROM,16KB RTC SRAM,and 1 Kbit eFuse.The chip supports a variety of low power consumption working states,which can meet the power consumption requirements of various application scenarios.
ES8388 is a low-power,cost-effective audio codec chip.It integrates 2 ADCs and 2 DACs,microphone amplifiers,headphone amplifiers,etc.,which can be widely used in various home smart devices,smart audio,story machine solutions And so on,is the
ideal solution for voice products.
The ESP32-A1S module provides a wealth of peripheral interfaces,including UART,PWM,SPI,12S,12C,ADC,DAC,SDIO and multiple GPIOs.
