这是最简单的一个案例，大家对ESP-NOW先有一个 简单的理解，关于ESP-NOW的管理设备，删除设备，扫描从设备，自动配对等，下一期再讲， 布置个作业， 大家可以在发送端添加一个按钮，接收端添加一个LED等，就可以实现一个遥控器的Demo了，快去尝试一下吧。

In the ESP32 module the built-in DAC and ADC are used for audio in and output, which provide just about enough resolution for voice communication. So why use ESP-NOW rather than WiFi or Bluetooth?

OTA (Over-The-Air) updates are a fantastic feature of the ESP32, and we’ve covered libraries that make it easy. But compared to those earlier projects, esp_ghota takes a different approach.

Applications First of all, the Pendrive S3 is simply a development board with ESP32-S3, which can be programmed from Platformio, Arduino IDE and CircuitPython.

Espressif is producing more and more chips with RISC-V cores. The comparatively powerful ESP32-P4 now comes on a 65-euro board for smart home technology.
