1. Support A acceleration ESP32-S3MCU adds vector instructions for accelerating neural network calculations and signal processing. developers use these vector instructions through the ESP- and ESP-NN libraries to achieve high-performance image recognition, voice wake-up and recognition applications. ESP-WHO and ESP-Skainet also support this feature. 2. ESP32-S3 has 45 programmable GPOs and common peripheral interfaces such as SP|, 125l2C, PWM, , ADC, UART, SD/MMC host controller and TWAITM controller. Fourteen of these GPOs can be configured as capacitive touch inputs for HM interaction. In addition, ESP32-S3 is equipped with an ultra-low power coprocessor (ULP), supports multiple low power modes, and is widely applicable to low power application scenarios 3. ESP32-S3 integrates 24GHz W-Fi (802.11b/g) and supports 40MHz bandwidth; its low-power Bluetooth subsystem supports Bluetooth5 (LE) and Bluetooth mesh, and can realize long-distance communication through Coded phy and broadcast extension. It also supports 2 Mbps Phy for increased transfer speed and data throughput. ESP32-S3's Wi-Fi and Bluetooth le radio frequency performance is superior, and it can work stably at high temperatures.
