(3) Micro HDMI port:
High-definition multimedia interface (High Definition Multimedia Interface,
HDMI) is a fully digital video and sound transmission interface, used to transmit
uncompressed audio and video signals. By connecting it to a display (or TV) equipped
with an HDMI interface, the content of the Raspberry Pi can be displayed. The HDMI
interface can transmit video and audio signals at the same time, so when we use it, we
don't need to connect speakers to the audio interface of the Raspberry Pi. If we really
need to play sound through the audio interface, we need to modify the operating
system configuration accordingly.
(4) USB2.0/3.0 port:
The Universal Serial Bus (USB) interface is the most common interface on a
computer. You can use it to connect devices such as keyboards, mice, USB flash
drives, and wireless network cards. When the number of USB ports is not enough, we
can also increase the number of USB ports through a USB hub.
(5) Audio port:
Audio interface (3.5mm headphone jack) When HDMI connection is not used,
you can use the standard 3.5mm headphone jack speakers or headphones to play audio.
At the same time, the interface also integrates a composite video interface with a
composite audio and video output function, which is generally used to connect to old
models of TVs, and is currently rarely used.
(6) MIPI CSI camera port:
The CSI interface can be used to connect the CSI camera to the Raspberry Pi via
a ribbon cable for easy video recording and image capture. Compared with the USB
camera, this camera module has better performance.
(7) USB-C 5V/3A power supply port:
The Micro USB power supply interface is one of the main power supply methods
of the Raspberry Pi. The rated voltage is 5V. The standard current requirements of
different versions of the Raspberry Pi are slightly different. For example: the 1B type
