This Module has another name: Gert-VGA-adapter, or Passive VGA adapter 666 for Raspberry Pi A+/B+/2B/3B/Zero
The Raspberry Pi has an HDMI port to connect a display.
If your monitor only has VGA, you have to use an adapter.
Because this requires a digital-to-analogue conversion, those adapters can be quite pricey, and they can draw lots of power.
As well as just allowing you to connect a VGA monitor natively.
And unlike composite video, the DPI interface can be run independent of the HDMI.
The software for dual screens is still under development.
Running two screens at maximum resolution will depend on the speed of GPIO.
This wasn’t possible on the Model A or B.
And there’s a catch: as the board uses most of your GPIO pins, you lose access to them.
All above are from raspberry pi official website.

這個模塊有另外一個名字:格特-VGA適配器,或被動VGA轉接器666樹莓派A + / B + / 2B / 3B /零
樹莓丕有一個HDMI端口連接顯示器。
如果您的顯示器只有VGA,你必須使用一個適配器。
因為這需要一個數字 - 模擬轉換,這些適配器可以說是相當昂貴的,他們可以抽籤的動力。
還有剛才讓你本地連接VGA顯示器。
而不像複合視頻中,DPI接口,可獨立運行的HDMI接口。
雙屏幕軟件仍處於開發階段。
在運行最大分辨率兩個屏幕將取決於GPIO的速度。
這是不可能的型號A或B.
而且這裡有一個問題:作為主板使用大部分的GPIO引腳,你失去了對它們的訪問。
