Perfect security mechanism: ESP32-S3 provides perfect security mechanism and protection measures for IoT devices to prevent various 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-interfering execution environments to implement 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 40 MHz bandwidth; its low-power Bluetooth subsystem supports Bluetooth 5 (LE) and Bluetooth Mesh, which can achieve long-distance communication through Coded PHY and broadcast extension. It also supports 2 Mbps PHY to increase transmission speed and data throughput. ESP32-S3 has excellent Wi-Fi and Bluetooth LE radio performance and 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 controller and TwAITM controller. 14 of the GPIOs can be configured as capacitive touch inputs for HMI interaction. In addition, ESP32-S3 is equipped with an ultra-low power coprocessor (ULP), which supports multiple low-power modes and is widely used in various low-power application scenarios software support: ESP32-S3 uses Espressif's IoT development framework ESP-IDF. ESP-IDF has successfully enabled hundreds of millions of IoT devices, has undergone rigorous testing and release cycles, and has a clear and effective support strategy. Based on its software architecture, developers easier to build applications or migrate existing programs to the ESP32-S3 platform with their familiarity with tools and Explore the capabilities of AI with the XiaoZhi AI Voice Chat Development Board, a DIY kit perfect for hobbyists and professionals alike, powered by a powerful ESP32-S3 processor Wi-Fi: Supports IEEE 802.11 b/g protocols Bluetooth: Low-power Bluetooth (Bluetooth LE): Bluetooth 5, Bluetoothmesh High power mode (20 dBm) Supports rates of 125 Kbps, 500 Kbps, 1 Mbps, 2 Mbps Colour:As Shown Material:plastic Due to different batches, there may be differences in product appearance and printed text, which not affect use Package Contents: 1 * AI Voice Chat DIY Kit Only the above package content, other products are not included.
