Power in and USB Host
The power input interface is a 2PIN PH2.54mm connector. The USB host is a 4PIN PH2.0mm connector.
The AV out is a 6PIN PH2.0mm connector. The Ethernet port is a PH2.0mm connector, 100M ethernet port. This video decoder board supports UDP TS video stream decoding, Decodifica client RTSP, and also RTSP server forward.
Data-uart and control-uart
Dati uart: 3Connettore PIN PH1,25 mm, TTL 3,3 V. When the video decoder board works paired with our video encoder module and Ethernet linker (senza fili o via cavo), the uart data of the encoder module will be transferred to this uart.
Controllo uart: 4Connettore PIN PH1,25 mm, TTL 3,3 V. This video decoder board system can be set up via this control uart with AT command.
LEDs and Keys
The extension port is designed for assembling keys and LEDs if necessary, it’s a 2.0mm 5*2PIN connector, please view the PCB silk printing for its signals (as the photo above).
| GUIDATO | Descrizione |
| LED di alimentazione | Light on when the board is normally powered |
| Video-LED | Blinks when the video stream is normally received and decoding |
| Record-LED | Light on when video is being recorded with a USB disk or TF card |
OSD_key
OSD key: attivare/disattivare lo stato della visualizzazione dell'OSD, and long press it to switch(more than 1s). the status will be kept after reboot. When the OSD status is on without any OSD data input from the data uart, the system will display video information (video bitrates, ecc.) on the video screen. When the OSD status is on with data input from the data uart, the system will display text information of the uart data on the video screen.
Rec_Key
Record key: switch button for video recording, short press to change its status. The system will automatically check the storage device(TF card or USB disk, priority TF card) after power on and start to record video when the storage device is inserted. Just press the button to stop or record again.

FAQ
Q: How can I use the Rec key to record the video?
UN: After the storage device is connected, the system detects the storage device and automatically records the video.
Q: Can I use the Rec_key pin?
UN: Connect a button between the REC_Key pin and the GND pin (if there is no button, simulate the button operation by short-circuiting REC_Key and GND), or use the MCU’s gpio to connect the REC_Key pin for control.
Q: Do you have an appropriate box for your video LAN modules?
UN: NO, se ne hai bisogno, we have to make one metal box for you, it has extra cost.
We only provide these two boards to customers as accessories. Customers will install them in their own iron boxes. Customers will also install other boards together, so the shell is made by the customers themselves.
Q: One of them has an FPGA that heats up during operation.
UN: It is normal for the operating temperature to be high during encoding and decoding. Our boards can pass high and low temperature tests at -40 gradi e 80 gradi. Se necessario, you can add your own heat sink, or add a cooling fan to the case. Whether it is very hot or not is also related to the local temperature and working environment. Heat dissipation can also be achieved by using thermal conductive adhesive to stick a small heat sink of appropriate size on larger ICs such as CPU and DDR.

I have been using this IP to HDMI CVBS H.264 video decoder board for a few months, e ha superato le mie aspettative. La qualità video è eccellente, with smooth 1080P output and minimal latency, making it perfect for real-time monitoring. Setting up via the web interface or UART commands is straightforward, and recording to a TF card or USB drive works seamlessly. The board is compact, robusto, and reliable, even under continuous operation. I highly recommend it for industrial or embedded video applications.
