应该是目前性价比最高的ESP32-S3开发板了，之前合宙卖29.9包邮的时候还行，现在49.9还不包邮😅
现在工作主力机逐步移动到Linux上面，所以简单记录一下
目录
VScode安装ESP-IDF插件
首先在插件栏搜索并安装ESP-IDF
安装完毕后会弹出配置页面，一般选择EXPRESS方式安装即可
接下来是选择要下载的ESP-IDF版本以及目录，版本选择建议选择最新版，我这里是5.2.1，如果github源下载不动，可以换成Espressif尝试，另外需要Linux上有安装python3环境，目前大多Linux发行版已经自带python3。配置完成后点击install安装
等待安装完毕，弹出欢迎界面就OK了
安装CH343驱动
ch343官方没有直接发布linux下的驱动文件，需要手动编译及安装
首先克隆下官方驱动仓库，并进入目录
$ git clone https://github.com/WCHSoftGroup/ch343ser_linux.git
$ cd ch343ser_linux/driver这里需要对驱动做一些修改，不然ESP-IDF无法识别到串口，其实就是修改下串口的名称
$ vim ch343.c找到ch343_tty_driver->name = "ttyCH343USB"，修改为ch343_tty_driver->name = "ttyUSB"
ch343_tty_driver->driver_name = "usbch343", ch343_tty_driver->name = "ttyUSB",保存后退出，使用make编译驱动，如果没有gcc的话要安装gcc，不再赘述
$ make
make -C /lib/modules/6.5.0-28-generic/build M=/home/miku39/Driver/ch343ser_linux/driver

make[1]: 离开目录“/usr/src/linux-headers-6.5.0-28-generic”编译完成后使用sudo make install安装驱动
$ sudo make install

cp -f ./ch343.ko /lib/modules/6.5.0-28-generic/kernel/drivers/usb/serial || true
depmod -a用lsmod查看所有驱动，有ch343的话表示安装成功，如果要卸载的话使用sudo make uninstall即可
$ lsmod

ch343 40960 0将开发板连接至电脑，查看有无设备驱动节点
$ ls /dev/ttyUSB*
/dev/ttyUSB0说明驱动已正常工作，回到ESP-IDF，随便新建一个项目，然后串口选择/dev/ttyUSB0即可
注意
有些情况下串口设备名称是ttyACM*，有些时候是ttyUSB*
