VGA666 Module For RPi

Description

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.
So our friend Gert van Loo (who developed the Alpha board that became the Raspberry Pi, 
and the man behind the Gertboard and Gertduino) has created a VGA adapter that uses the Pi’s GPIO.

This wasn’t possible on the Model A or B

but now the B+ exposes 40 GPIO pins, there’s more to play with. 
As well as just allowing you to connect a VGA monitor natively, it also means you can use it as a secondary monitor alongside HDMI. 
And unlike composite video, the DPI interface can be run independent of the HDMI. 
The software for dual screens is still under development, but we expect that to arrive in the next couple of weeks. 
Running two screens at maximum resolution will consume SDRAM bandwidth,and is yet to be tested. (And there’s a catch: as the board uses most of your GPIO pins, you lose access to them.)
Dom has been working on the software side and the new DPI (read: VGA) driver software has been added to the latest release.

How to wire it up

Plug into GPIO as following Picture:

How to use it

Edit /boot/config.txt file with vim.tiny or other editor. and modify as following:
framebuffer_width=800
framebuffer_height=600
dpi_group=2
device_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

You should disable all of GPIO pin's function so that it can work properly. we strongly recommend that you use 800x600 resolution.
the highly resolution will slow down your Pi and cost more RAM.
