1. The ESP32-S3 MCU supports acceleration through vector instructions for enhanced neural network calculations and signal processing. Developers can utilize these vector instructions via the ESP-DSP and ESP-NN libraries to achieve high-performance image recognition, voice wake-up, and speech recognition applications. ESP-WHO and ESP-Skainet frameworks also support this functionality. 2. The ESP32-S3 features 45 programmable GPIOs and standard peripheral interfaces including SPI, I2C, PWM, RMT, ADC, UART, SD/MMC host controller, and TWAI controller. Fourteen GPIOs can be configured as capacitive touch inputs for human-machine interaction. Additionally, the ESP32-S3 includes an ultra-low power coprocessor (ULP), supports multiple low-power modes, and is suitable for various low-power application scenarios. 3. The ESP32-S3 integrates 2.4 GHz Wi-Fi (802.11 b/g/n) with support for 40 MHz bandwidth. The low-power Bluetooth subsystem supports Bluetooth 5 (LE) and Bluetooth Mesh, enabling long-range communication through Coded PHY and advertising extensions. It also supports 2 Mbps PHY for increased transfer speed and data throughput. The Wi-Fi and Bluetooth LE radio frequency performance is excellent, ensuring stable operation at high temperatures.
