Supports AI acceleration ESP32-S3 MCU has added vector instructions for accelerating neural network computation and signal processing. AI developers can use these vector instructions through the ESP-DSP and ESP-NN libraries to achieve high-performance applications such as image recognition, voice , and recognition. ESP-WHO and ESP-Skainet will also support this feature. A comprehensive security mechanism ESP32-S3 provides comprehensive security mechanisms and protection measures for IoT devices, preventing malicious attacks and threats. It supports flash encryption based on -XTS algorithm, secure boot based on algorithm, digital signature, and HMAC. ESP32-S3 also adds a World Controller module, which provides two non-interference execution environments and implements a trusted execution environment or permission separation mechanism. Wi Fi+Bluetooth 5 (LE) ESP32-S3 integrates 2.4 GHz Wi Fi (802.11 b/g) and supports a bandwidth of 40 MHz; Its low-power Bluetooth subsystem supports Bluetooth 5 (LE) and Bluetooth Mesh, and can achieve long-distance communication through Coded PHY and broadcast extensions. It also supports 2 Mbps PHY to improve transmission speed and data throughput. The Wi Fi and Bluetooth LE radio frequency performance of ESP32-S3 is superior, and it can work stably even at high temperatures. Rich IO interfaces ESP32-S3 has 45 programmable GPIOs and commonly used peripheral interfaces such as SPI, I2S, I2C, PWM, , ADC, UART, SD/MMC host controllers, and TwAITM controllers. Among them, 14 GPIOs can be configured as capacitive touch inputs for HMI interaction. In addition, the ESP32-S3 is equipped with an Ultra Low Power Coprocessor (ULP), which supports multiple low-power modes and is widely suitable for low-power application scenarios. software support ESP32-S3 adopts 's IoT development framework ESP-IDF. ESP-IDF has successfully empowered billions of IoT devices, gone through rigorous testing and release cycles, and has clear and effective support strategies. Developers, based on their software architecture and familiarity with tools and , will be more likely to build applications or migrate existing programs to the ESP32-S3 platform This series of programs is backward compatible, for example, N4 programs can run on N&N16 without modification. Wi Fi: Supports IEEE 802.11 b/g protocol Supports 20 MHz and 40 MHz bandwidth in the 2.4 GHz frequency band, supports 1T1R mode, and has a data rate of up to 150 Mbps. Wireless Multimedia (WMM) Frame Aggregation (TX/RX A-MPDU, TX/RX A-MSDU) Immediate Block Fragmentation/reassembly Beacon automatic monitoring (hardware TSF) 4 x Virtual Wi Fi interface Simultaneously supports Infrastructure Station mode, SoftAP mode, and Station+SoftAP hybrid mode. Please note that when ESP32-S3 is scanned in Station mode, the SoftAP channel will change simultaneously Antenna diversity 802.11 Bluetooth: Low power Bluetooth LE: Bluetooth 5, Bluetooth mesh High power mode (20 dBm) Supports speeds of 125 Kbps, 500 Kbps, 1 Mbps, 2 Mbps Advertising extensions Multiple Advertisement Sets Channel Selection Algorithm # 2 Wi Fi and Bluetooth coexist, sharing the same antenna CPU and storage: Xtensa Due to different batches, the appearance, color, and printed words of the product , which does not affect its use.
