While packing up my things, I came across this little gadget and took it out to play with.
Orange Pi Zero Plus (512MB)
H5 @ 1.2GHz, performance is decent.
512MB DDR3.
DC 5V DC-IN, it can be powered directly by DC, USB, or Ethernet.
Some features, let’s talk about this CVBS.
It has a decent network function; the built-in WiFi is somewhat weak, but it has OTG, USB, etc., so you can add a network card and drivers.
There is one USB 2.0 host function and one USB 2.0 OTG, with two USB ports available on the pins.
CVBS is a widely used standard, also known as baseband video or RCA video, which is the traditional image data transmission method for the National Television System Committee (NTSC) television signal in the USA. It transmits data using an analog waveform. Composite video contains chroma (hue and saturation) and luminance (brightness) information, which are synchronized in the blanking pulse and transmitted in the same signal.
It is a format of an analog television program (image) signal combined with an audio signal before being modulated onto a radio frequency carrier. In fast-scanning NTSC television, very high frequency (VHF) or ultra-high frequency (UHF) carriers use amplitude modulation for composite video, resulting in a signal approximately 6MHz wide. Some CCTV systems use coaxial cables to transmit composite video over short distances, while some DVD players and video cassette recorders (VCRs) provide composite video input and output through audio sockets, also known as RCA connectors. In composite video, interference between chroma and luminance information is inevitable, especially when the signal is weak. This is why long-distance use of VHF or UHF NTFS television stations with old whip antennas, “rabbit ears,” or outdoor “aerials” often contains false or shaking colors. CVBS is a relatively old display method, more accurately the first generation of video display output methods (the second generation is S-VIDEO, the third generation is VGA, the fourth generation is DVI, and the fifth generation is HDMI).
A picture is worth a thousand words; this yellow port allows us to do some interesting things, doesn’t it?
This is called the Linux kernel function support matrix; all upper-layer applications we build must be supported by the Linux kernel, which is the source of all magic.

Color quickly represents something.
For this Linux kernel, you can add things yourself.

And the features that have been added so far.
https://www.wireguard.com/And a VPN has been added.
I can only say that after SSR and V2Ray, it is the king. I can’t elaborate more.
This place’s jio can add expansion boards.
Looks like this.
Combine and make one.
As an A-type socket, one USB host port is usb1.
usb2 and usb3 can be obtained through solder holes. USB OTG can be obtained via micro USB.

I am throwing up some materials.
Today I went out, and that’s all I have for the article. More updates tomorrow.
