NOTE
2.3 Power Tree
J41 and J9 can be used to supply the EVK Board. A DC 5V external power supply also can be used to supply the EVK Board by
connecting two pins in J1. Different power supply need to configure different Jumper setting of J1.
Table 4 shows the details:

For some computers’ USB, it cannot support 500ma before establishing communication. In this case, it is
recommended to replace the computer.
