将传感器连接到 NVIDIA Jetson Nano
我有 8 个传感器，我需要您对哪个更好的意见：将所有传感器直接连接到 nvidia Jetson Nano 或将它们连接到另一个微控制器板（如 arduino 或 esp32），然后通过串行端口将其数据发送到 Jetson Nano 进行数据分析和操作决策？为什么？ 预先感谢您！
I have 8 sensors and I need your opinion on which is better: interface all sensors directly to nvidia Jetson Nano or interface them to another microcontroller board like arduino or esp32 then send their data with serial port to th Jetson Nano for data analysis and action decision ? and why ?
Thanks you in advance !

在 Jetson 上，您有 GPIO 引脚、I2C 总线，并且可以使用 Arduino 作为子处理器。
GPIO 很方便，但需要 Jetson 来完成所有工作。
I2C 总线很常见，并且有许多传感器可用并且可以菊花链方式连接。传感器需要 I2C 接口。
Arduino 只需一个 USB 端口即可卸载处理。它们还有许多不同的风格/尺寸，并为不同的传感器提供了大量的接口选择。
需要更多地了解您的传感器才能拨打电话。
On the Jetson, you have the GPIO pins, the I2C buses and you can use an Arduino as a sub-processor.
The GPIO is convenient but requires the Jetson to do all the work.
The I2C bus is common and many sensors are available and can be daisy chained. The sensor needs an I2C interface.
The Arduino just needs a USB port and can offload processing. They also come in many different flavors/sizes with plenty of interface choices for different sensors.
Would need to know more about your sensors to make the call.
