Question one:
About power supply?

1. It is recommended to use the store’s 5V3A or 5V4A DC power supply to power the development board. Other power supplies have not been tested and cannot be guaranteed

2. When Type-C is used for power supply, you need to use an independent 5V3A or 5V4A power supply with a power head. If a separate Type-C cable is connected to the computer for power supply, the motherboard will be insufficiently powered and cannot start normally

3. In the case of high load such as many peripheral connections or a screen connected to the MIPI interface, it is recommended to use it with the store’s 5V4A power supply. The 5V3A power supply may be insufficient.
