[Disassemble] Hai Meidi H7 evaluation, dismantling articles

When H7 arrived yesterday, it could not wait to disassemble the main control. To tell the truth, when the main control was A31S, it was a bit disappointing. The original SDk of A31S does not support 1080P point-to-point output and 4K decoding. However, 4K decoding is also printed on the package.

The front and back of the motherboard. Still adopts the red PCB that Hai Meidi uses consistently, the layout also basically adopts the standard layout of the whole aspiration. There is a 1mm thick heat sink on the CPU that has been removed for ease of photography

Master, All A31S. As mentioned earlier, the original A31S does not support 1080P point-to-point video and 4K video decoding. But the actual test, all home 4K video can be played normally, 1080P point-to-point is also no problem. It seems that Quan Zhi finally wanted to understand, no longer limited by the SDK, forced to open the level between A31 and A31S. The low-end quad-core can now be used perfectly on box products. In addition, the original BD-ISO playback support of Quan Zhi and Hai Meidi's optimization of the local player and various LAN protocols can be said that the local video basically takes it all and the LAN playback is perfect. This time, Haimei Di's all-in-one firmware also fixed a bug on the previous Q2 II and J2 II, that is, when playing in LAN, it was to call the official record player of Quan Zhi. The video on the USB device was played. Di Bug's own player's Bug, all use Hai Meidi's own player, which makes the selection of subtitles, pulling video time is more user-friendly. However, there are also regrets that the H7 of the A31S still maintains the shortcomings of Q2 II and cannot use AirPlay Mirror.

Flash memory, NADN, Foresee, model NCTSTS76-08G, capacity 8GB.

Memory, SK Hynix, South Korea's Hynix, models H5TQ4G63MFR-PBC, DDR3 1600, 96Ball package, single 512MB, two composed of 1GB of memory.

The Wi-Fi part is still the Realtek 8188ETV, a low-power version, and most boxes use this solution. Specifications, 802.11 B/G/N, USB 2.0 interface, under N, maximum bandwidth 150Mbps.

The wired network card, Taiwan ICPLUS, model IP101GA, provides a 10/100Mbps wired connection.

USB controller, Taiwan Creative Technology, provides external USB interface support. Supports USB storage devices, USB handles, etc.

Power Supply Control IC, Shenzhen Core Smart, the power control IC used on QuanZhi's quad-core platform.

CVBS output controller, model GM7122, Chengdu Guoteng. Used to provide the analog output function of the box.

The network transformer, model M1601AG, can isolate different levels of different network devices connected by a network cable to prevent different voltages from transmitting damaged devices through the network cable. In addition, the device can also play a role in lightning protection.
