Attention:
1. To download the USB-TYPE-C program, you need to install the driver for CH340, which is included in the driver package.
2. Regarding computer power supply, it is not recommended to use a laptop USB port. Instead, use the USB 3.0 port of a desktop computer because the screen is in WiFi mode and the instantaneous current is relatively high. If the computer still cannot be powered, you can try using a mobile phone charger to power it.
