Seeking Recommended 5"–7" Displays for UNO Q (ABX00173) – Tested Setup

Hi everyone,

I’ve recently started working with the Arduino UNO Q (ABX00173) and I’m looking to transition from the built-in LED matrix to a dedicated external display. Since this board is a hybrid SBC/MCU powerhouse, I’m specifically looking for a compact display in the 5-inch to 7-inch range.

My goal is to run a standalone Debian environment with a responsive GUI, so I have a couple of questions for those who have already successfully integrated external screens:

  1. USB-C Video (DP Alt Mode): Has anyone tested specific 5" or 7" portable monitors that work well with a USB-C PD dongle? I'm aiming for the optimal 1280x720p resolution as mentioned in the Official UNO Q Datasheet.
  2. MIPI DSI via JMEDIA: Does anyone have experience using the 60-pin JMEDIA connector for a DSI display? If so, which ribbon cables or carriers are you using?
  3. Power Stability: Since the board requests a 5V / 3A contract over USB-PD, have you encountered any undervoltage issues when powering both the UNO Q and the display from the same hub?

I’m particularly interested in displays that are "plug-and-play" with the pre-installed Debian Bookworm image. If you have a specific model or brand that worked for you, please share your setup!

Thanks in advance for the help!

I use the HDMI port to drive my 15.6" screen.

I am planning to operate my UNO Q as SBC for which I want use my HDMI TV as a monitor. Before I connect the TV with dongle, I have wanted to test it using HDMI port of my PC. Unfortunately, I cannot operate my HDMI TV from my PC as a duplicate screen (Window Key + P and then select Extend). Do you have any advice how I can make my HDMI TV working before I connect it with SBC/dongle?

I have used my TV as a display a few times, connected by HDMI, but only for a Raspberry Pi. If I want to use it with my Mac, I use the built-in wireless functions that come with it.
In my shop, I have an HDMI switch with Windows, Pi, Linux, and now UNO Q, but it's just one Windows display, no extension.

Thank you.

Hi @nhilson ,

Welcome to the forum..

The UnoQ is still a bit new..

Not allot of third party add ons, might be able to use an rpi screen..

haven’t seen anything on the mipi ports..

I’ve been running in SBC mode, typical computer monitor, I’m running 1080p no issues..

No power issues to speak of..

Not using AppLab, installed Geany and set that up..

still haven’t taken my 4g out of the box happy with the 2g..

good luck.. ~q

I know this is an old topic, but thought I should add an update on this subject:

The Arduino UNO Media Carrier will provide convenient connectivity between the "high speed" headers on the bottom of the UNO Q board and MIPI DSI displays using a standard 22 pin flat flex cable. You can find information here:

https://docs.arduino.cc/hardware/uno-media-carrier/

The product is not yet available for purchase, but should be released in the near future. If anyone is interested, you can click the "Email me when available" button on the product listing to receive a notification once it is available:

I just received my uno q media carrier
I have a 5" waveshare display, but it doesn't work ... apparently the wrong one. it works fine with rpi. It would be great to support this one as it doesn't require separate power cable, and it is inexpensive.

Hi @dhoward1. The following display models are supported for use with the UNO Media Carrier:

How / Where do I get the 5V power needed by the display?
There are low power Waveshare 5" capacitive displays that don't require separate power. They get power over the MIPI cable. They works with rPi 4/5 etc. It would be ideal to support them as they are simpler to use. What needs to be done to support this display?

The Waveshare display should come with a power cable:

The large connector has 0.1" pitch, which allows it to plug directly onto male headers. Fortunately the perfect male headers are present on the top of the UNO Q board:

So just plug the cable onto the three pins on the SPI header indicated in the diagram above. Make sure to get the orientation of the cable right. Fortunately the shape of the housing makes it impossible to plug in reversed, so this shouldn't be too much of a concern.

You may be interested in this independent project created by one of the original founders of Arduino, David Cuartielles:

Please note that the Arduino company does not officially support any displays other than the ones I listed in my previous reply. So use of David's project is very much an "at your own risk" sort of thing. Of course you are always welcome to request assistance with any Arduino endeavors here on the forum, regardless of whether or not you are following the "golden path" provided by Arduino.
