Product description: Seeed Xiao ESP32-S3 - WiFi / Bluetooth - Seeedstudio 113991114
The Seeed Xiao is a small module equipped with a powerful ESP32-S3 chip with a dual-core Xtensa 32-bit LX7 processor clocked at 240 MHz . It enables wireless communication at 2.4 GHz WiFi and Bluetooth 5.0, draws only 14 μA in deep sleep mode, and simultaneously manages battery charging. It is ideal for IoT applications. The Seeed Xiao ESP32-S3 chip is equipped with 8 MB of PSRAM and 8 MB of Flash memory. The board also includes a battery charging circuit. There are 11 digital I/O pins , which can also be used as PWM pins, and 9 analog I/O pins, which can be used as ADCs. It supports serial communication ports such as UART, I2C, and SPI, including I2S (Internet Information Services). An external antenna is also included. The module can be programmed in the Arduino environment.
