我是arduino的新手，我最近买了一个Nano，当我尝试上传代码时，它会抛出这个错误:
`Arduino: 1.8.13 (Windows 10), Board: "Arduino Nano, ATmega328P (Old Bootloader)"
Sketch uses 924 bytes (3%) of program storage space. Maximum is 30720 bytes.
Global variables use 9 bytes (0%) of dynamic memory, leaving 2039 bytes for local variables. Maximum is 2048 bytes.

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

我试过改变程序员，改变处理器到旧的引导加载程序;都是标准的东西。什么都没起作用。如有任何帮助，不胜感激
我最近在IDE 2.0.3中遇到了同样的问题，不得不转到tools/Processor/ATmega328P (Old Bootloader)。
这将比特率从115200更改为57600，并允许对纳米进行编程。
测试其他端口，以及其他USB连接线。如果你从中国买这个nano，也许它有CH3040 usb驱动程序(这是一个便宜的中国usb通信芯片)。如果这是真的，下载这个驱动程序，没有它是不能工作的中文nano。
祝你好运!
Arduino Nano使用与UNO中使用的CP2102不同的CH340G驱动程序所以你需要安装正确的驱动程序，并检查COM端口的内部驱动程序部分。如果你已经烧录了新的引导程序，它不会导致任何上传问题
作为最后的手段，您可以使用Arduino作为ISP来编程NAno请查看这篇文章
