Gert-VGA-adapter Passive VGA adapter 666 for Raspberry Pi 2/3/4

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-analog 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 independently 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.

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

Passive VGA Features:

• You should disable all of GPIO pin’s function so that it can work properly.
• we strongly recommend that you use 800×600 resolution.
• the high resolution will slow down your Pi and cost more RAM.

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.
The color of the item might be slightly different from the picture shown, which mainly lies in different light effect and computer monitor. Please give us your understanding. Thank you!
