In addition, RPi also needs a network cable used to connect it to wide area network.
All of these components are necessary. Among them, the power supply is required at least 5V/2.5A, because
lack of power supply will lead to many abnormal problems, even damage to your RPi. So power supply with
5V/2.5A is highly recommend. SD Card Micro (recommended capacity 16GB or more) is a hard drive for RPi,
which is used to store the system and personal files. In later projects, the components list with a RPi will
contains these required components, using only RPi as a representative rather than presenting details.
