ESP32-S3 is a dual-core XTensa LX7 MCU, capable of running at 240 MHz. Apart from its 512 KB of internal SRAM, it also comes with integrated 2.4 GHz, 802.11 b/g/n Wi-Fi and Bluetooth 5 (LE) connectivity that provides long-range support. It has 45 programmable GPIOs and supports a rich set of peripherals. ESP32-S3 supports larger, high-speed octal SPI flash, and PSRAM with configurable data and instruction cache.

AI Acceleration Support
ESP32-S3 has additional support for vector instructions in the MCU, which provides acceleration for neural network computing and signal processing workloads. Developers can take advantage of these vector instructions through ESP-DSP and ESP-NN libraries to optimize their applications. ESP-WHO and ESP-Skainet SDKs will also support this acceleration.
Wi-Fi + Bluetooth 5 (LE)
ESP32-S3 supports a 2.4 GHz Wi-Fi (802.11 b/g/n) with 40 MHz of bandwidth support. The Bluetooth Low Energy subsystem supports long range through Coded PHY and advertisement extension. It also supports higher transmission speed and data throughput, with 2 Mbps PHY. Both Wi-Fi and Bluetooth LE have superior RF performance that is maintained even at high temperatures.
Rich Set of IO Peripherals
ESP32-S3 has 45 programmable GPIOs, SPI, I2S, I2C, PWM, RMT, ADC, DAC and UART, SD/MMC host and TWAITM. In total, 14 GPIOs can be configured as capacitive touch input for HMI applications. Apart from all these peripherals, however, ESP32-S3 is also equipped with an ultra-low-power (ULP) core that supports multiple low-power modes in a variety of such use-cases.
Security
ESP32-S3 provides all the necessary security requirements for building securely connected devices, without requiring any external components. It supports AES-XTS-based flash encryption, RSA-based secure boot, digital signature and HMAC. ESP32-S3 also has a “World Controller” peripheral that provides two fully-isolated execution environments, which enables the implementation of a trusted-execution environment or a privilege-separation scheme.
Mature Software Support
ESP32-S3 is supported through Espressif’s popular ESP-IDF platform that already powers millions of devices on the market. ESP-IDF comes with rigorous testing, regular updates and an unparalleled support policy. Based on ESP-IDF’s mature software architecture, developers can easily build applications anew or migrate their own applications to the ESP32-S3 platform, and continue working with the trusted ESP-IDF tools and APIs.
ESP32-S3-WROOM-1-N8R2 is a powerful, generic Wi-Fi + Bluetooth LE MCU module that have Dual core CPU, a rich set of peripherals, provides acceleration for neural network computing and signal processing workloads.
It is an ideal choice for a wide variety of application scenarios related to AI + Internet of Things (AIoT), such as wake word detection and speech commands recognition , face detection and recognition, smart home, smart appliance, smart control panel, smart speaker etc.
