Giới thiệu Mô Đun Raspberry Pi 3 B / 2 / B + VGA666 Chuyên Dụng tại Lotte Market

This module has another name: gert-vga adapter, or passive vga adapter 666 raspberry pi b+

Raspberry pi has a hdmi port connection monitor.If your monitor is only vga,Then you have to use an adapter to connect your monitor,Because the number-to-number adapter is more expensive and does not fit the particular environment used by rashberry pi,So we adopted this solution for rashberry pi.

The vga 666 adapter device cannot support the rashberry pia and b boards because the number of pins in gpio does not match.



Now 40 gpio pins are available in raspberry pi b+, raspberry pi 2, type b, raspberry pi 3.

Using this module, you can implement a local connection vga monitor, which also means you can use it as an auxiliary monitor next to hdmi.Unlike composite video, dpi interface, can run independently of hdmi interface.


Dual-screen software is still in the development stage and will soon be officially compatible.


Running the maximum resolution two screens consumes the bandwidth of sdram and is yet to be tested. (and there's a problem: using most of the gpio pins as the main board means that none of the gpio's specific functions can be used because of occupancy.)


Product characteristics:
L vga output supports the same resolution as hdmi

L support resolution to 640x480 to 1920x 1024 with 60fps

L at the highest resolution pixel quality is almost as good as hdmi

L 6 bits of each channel have one of the largest 262144 colors

L easy to installl and configure, plug and play

L you can use it as an auxiliary monitor next to hdmi

L size: 64.00mm x 32.24mm

L weight: 16.48 g

Method of use:
Follow the diagram below to connect raspberry pi gpio pins, pay attention to direction and the strength of the plug.



The tf card that burned the latest system (which currently supports only the raspian system) is then inserted into the computer, the config. txt file in the tf card/boot partition is opened through the editor, and the configuration is modified to read as follows:

Framebuffer _width = 800
Framebuffer _ right = 600
Dpi _ group = 2
Vice _ tree = bcm2710-rpi-3-b.dtb
Dpi _ mode = 86
Dtparam = i2c _ arm = off
Dtparam = spi = off
Dtparam = uart0 = off
Dtparam = uart1 = off
Dtoverlay = pi3-disable-bt-overlay
Dtoverlay = vga666
Enable _ dpi _ lcd = 1
Display _ default _ lcd = 1
Force _ pwm _ open = 0
Dtparam = audio = on
Start _ x = 1
Gpu _ mem = 128

Then save the exit, insert tf cards into raspberry pi, and see the graphics by using vga cable to connect the display and vga interface with the vga 666 module, and then start raspberry pi.

Here, we emphasize that the framebuffer in configuration recommends using the 800 and 600 we provide, because if the numbers get bigger, there are some delays.It will affect the viewing effect.
