Built-in 3G is not supported. If only one USB interface uses keyboard holster or small stereo, external 3G routing cannot be used. . .

I don't support network cable link, so I have to buy another router with unlimited traffic. To be honest, it's not cost-effective.

There are too few interfaces, and none of the supported ones are supported. . .

999 is expensive, the CPU performance is average, and now the memory is cheap.

Gravity sensing only supports three sides, and it is also possible to support four sides.

At present, the official firmware is not perfect, so it is not recommended to buy it!

Now the performance of tablets and the like is not perfect enough, so we can wait and see ~
