关于ESP32-S3芯片优势

首先ESP32-S3是双核的并且带有WIFI和蓝牙BLE5.0无线功能，忽略双核、WIFI和蓝牙功能，与比较流行的ST的系列F1对比性能如下所示。

上述对比都是核心对比，ESP32-S3通过可以外扩RAM和FLASH例如N8R2就是外扩的标识，N8R2即外扩8MFLaSh与2MRAMN16R8即外扩16MFlash与8MRAM。性能方面可以说锤爆对比选项。源地VCC heVCC-GND

USB OTG

When using the on-chip PHY, the differential signal pins USB_D- and USB_D+ of the USB OTG are multiplexed with GPIO19 ~ GPIO20, RTC_GPIO19 ~ RTC_GPIO20, UART1 interface, and SAR ADC2 interface via IO MUX.
