与 ESP32 中的相比，这应该意味着非常低的功耗和更高的处理能力。 ESP32-S2 还能够在不使用时动态关闭 Wi-Fi 收发器以节省电量。 即使在 Wi-Fi “开启” ping 路由器的情况下，这也允许低功耗。 数据表讨论了在 1% 占空比时仅为 5uA (!!) 和 24uA 的低功耗模式。

The esp32-hal-ledc.* files provide helper functions to set up the hardware PWM generator, and with these libraries, getting a 16-bit LED fade in straight C or “Arduino” is easy.
