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

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. Best regards, Shaynee Freenove Support Team

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

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.

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

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. Best regards, Shaynee Freenove Support Team

Can I plus this into the DSI slot on an Orange Pi 5 Plus?

Wollte mir ein Touchdisplay für einen Raspberry Pi für meinen 3d Drucker kaufen. Dieses display ist perfekt. Einfach zu installieren, Treiber sind schnell heruntergeladen, es gibt einen Knopf mit welchem man verschiedene Helligkeitsstufen einstellen kann, touch reagiert super und die Farben sind einfach Top. Fast schon zu gut für den Preis.

この手の商品ではあるあるだと思いますが、同封の取扱説明書と実際の製品が異なって届きました。説明書では「基板上のポゴピンを介してラズパイ本体から電源供給するので、接続を確認しろ」との表記がありましたが、実際にはそのようなピンどころかパターンすらありませんでした。不安ながらリボンケーブルで接続したところ問題なく映像出力及びタッチ操作が可能でした。映像自体はきれいで、タッチ操作の感度も問題ないため☆5とします。

Un display touch con un’ottima risposta al tocco, la risoluzione è sufficiente per utilizzi standard (ad esempio domotica, oppure per realizzare un semplice stream deck come nel mio caso). Date le dimensioni e la risoluzione di 800x480 pixel, non lo consiglio come sostituto di un tablet o simili, nonostante sia ben leggibile e con retroilluminazione (che si può spegnere con un pulsante sul bordo del display). Il monitor arriva con tutti i cavi necessari per i vari modelli di Raspberry, ma senza una custodia esterna: sono presenti solo due piccoli supporti da avvitare sul retro del monitor che consentono di tenerlo in posizione verticale e leggermente inclinata, nessuna protezione per l'elettronica (foto); in effetti il produttore lo dichiara compatibile "solo per sperimentazione". Messo in funzione da un paio di mesi, anche se non utilizzato spesso, finora si è dimostrato affidabile.

Couldn't be easier. Plug it in, and that's it. Perfect. Screen looks good, it's not super high res or anything but it's bright and clear. Touch works well. Power draw running rpos is about 2.7 to 3.3 watts, actually pretty good. Nothing to complain about here, this is a great little screen. Note! Raspberry-pi OS supports touchscreen but NO WAY TO RIGHT CLICK.
