VGA 666 Adapter Board For Raspberry Pi 3B / 2B / B+ / A+

Desricption:

• It is a neat and very useful solution for using a VGA screen/monitor with your Raspberry Pi and is far cheaper than an HDMI to VGA adapter or similar. The VGA connection is driven natively in hardware over the GPIO pins (using a parallel interface) and uses around the same CPU load as the HDMI connection on board. It is capable of displaying 1080p60 VGA video with no CPU load. It is also possible to drive this interface at the same time as the HDMI connection, so a dual screen set up is also possible. 

Please Note. This add on board uses all but 6 of the GPIO pins so it may not be possible to use other add on boards at the same time as the VGA adapter. 

Note: Raspberry Pi main board is not included.

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.
