Support A acceleration ESP32-S3 MCU adds vector instructions for accelerating neural network calculations and signal processing. Developers can use these vector instructions through the ESP-DSP and ESP-NN libraries to achieve high-performance image recognition, voice wake-up, and recognition applications. ESP-WHO and ESP-Skainet will also support this feature. ESP32-S3 has 45 programmable GPIOs and common peripheral interfaces such as SPI, I2C, PWM, RMT, ADC, UART, SD/MMC host controller, and TWAI controller. Fourteen of these GPIOs can be configured as capacitive touch inputs for HMI interaction. In addition, ESP32-S3 is equipped with an ultra-low power coprocessor (ULP), supports multiple low power modes, and is widely applicable to various low power application scenarios. ESP32-S3 integrates 2.4 GHz Wi-Fi (802.11 b/g/n) and supports 40 MHz bandwidth; its low-power Bluetooth subsystem supports Bluetooth 5 (LE) and Bluetooth mesh, and can realize long-distance communication through Coded PHY and advertising 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.
