Question 1

I keep getting "Low Voltage Warning" on raspberry pi 4, why?

Accepted Answer

Dear customer,

Thank you for choosing Freenove. We are fully responsible for any concerns.
The main reason of this warning is the use of incompatible power supply, or an issue in the power cable

If you have any concerns, please feel free to contact us.

Question 2

Is the power derived from the flat flex cable? it doesn't look like there is any usb or barrel jacks on the monitor.

Accepted Answer

On the one I bought, a 7-inch IPS display, there are two (1 positive and 1 negative) spring loaded (pogo pins) contacts on the LCD that make contact with the +5V and Ground pins on the bottom of the GPIO header when you mount the RPi onto the provided standoffs. GPIO pins 4 and 6. Those pins are still available to use on the top of the GPIO header too.
Alternatively, there was a 2-pin power cable and longer ribbon cables included with the one I bought, for remote mounting the Raspberry Pi some small distance (3-4 inches) away from the LCD display.

Question 3

How do I rotate the touchscreen matrix of this display for portrait mode? I have tried edev and /boot/config.txt nothing works

Accepted Answer

Dear customer,

Thank you for choosing Freenove. We are fully responsible for any concerns.
There are two kinds of display direction rotation: FKMS mode direction rotation and
traditional graphics mode direction rotation.
Because there are many steps, only the second method is sent. If you have any more questions, please contact us by email and we will send you a PDF file.

Method 2: Traditional graphics mode
By default, the Raspberry Pi 3, 2, and 1 series use traditional graphics mode.
Raspberry Pi 4B can also use traditional graphics mode, just in /boot/config.txt file
under the Pi 4:
dtoverlay=vc4-fkms-v3d
Comment out, as shown (Traditional graphics mode is generally not recommended
on Raspberry Pi 4B). In traditional graphics mode, this can be done by adding it at
the end of the /boot/config.txt file:
display_lcd_rotate=x（x=0,1,2,3,0x10000,0x20000）
To set the display orientation, reboot is required to take effect .

If you have any concerns, please feel free to contact us.
