Nice post, good sound.

Very cool! Thanks for sharing.

I am currently working on a simple animation panel (64x32 pixels) that will include a MP3 player for my Grandkids. The idea is to allow them to generate some images that can be animated onto a fixed background image (think simple flip books with some editor tools to provide side scrolling). Tie in some triggerable sound clips to provide entertain sound bites.

Good post.

insightful post thanks ! I was a bit disappointed that object classes did not include "shark", "yellow rubber duck", "deer", "squirrel" , and "sasquatch" :-)

I was also surprised at the webcam frame rate, its alot faster than I would've guessed. I'm always thinking for object detection a webcam isnt fast enough, Arducam publishes a 120 fpm. The raspberry pi AI camera tho is comparatively slower than both when used at full resolution.

RE: Arduino Uno Q - Standalone Operation

so default it boots up into ubuntu without loading anything ? then some setup to enable features and IP address ? Its interesting, so 2 operations running the same AppLab login ?

Hi,

you said: "USB problem"...

Last week I purchased a Nano R4 at Farnell.

For the first check: I just unboxed my new Nano R4, connected on the USB, started the Arduino IDE, checked the right board, selected the connected USB-Port, then I read the board information.

Hi,

you mentioned: "...USB problem"...

My first impression.

Last week I bought a Nano R4 from Farnell.

For my initial check: I unpacked my new Nano R4, connected it via USB, started the Arduino IDE, selected the correct board, chose the connected USB port, and then read the board information.

The board works perfectly, and I was able to get it up and running in just a few minutes.

Of course, I made sure to install the latest drivers in the Arduino IDE.

This applies particularly to the CMSIS and JLink drivers; I installed the original drivers for each.

Yes, and Microsoft forced us to buy a new PC last October because of Windows 11. Anyway, I'm using Win11 Pro and connecting the board to the PC's USB 3.0 port.

The board already has an RTOS installed, so it's essentially plug-and-play, making it easy to get the board up and running. -> Arduino IDE, last Version.

I'm not a fan of unnecessary experimentation when it comes to setting something up for the first time.

Only after that can I experiment, including with software drivers on the board.
That way, if something is configured incorrectly, you can revert to a working setup. That also means backups, backups...
The Nano R4 is new to me, so I'm really looking forward to learning a lot.

I'm very curious to hear about your great experiences with the Nano R4!

Best Regard

Gerald

[mention:dc11ece8204f479e8dce2a47a33b20d3:e9ed411860ed4f2ba0265705b8793d05] Nice write up. I'm sure there are walk throughs on the internet - but I actually read yours. I feel more prepared for when I finally buy one of these.

Nice walk through of the capabilities.

Nice. You make it look easy.

Thanks for sharing your roadtest experience. Looks like out of the box, Arduino comes preloaded with examples and some cool LED matrix animation.

Small suggestion may be light up the LED between 24 and C with to denote the temperature degrees symbol. The LED matrix looks handy, now we don't to look for an external display.

I thought of exploring the Arduino App Lab before I get my hands on with Arduino UNO Q but looks like they stopped us here unlike the Arduino IDE where we can explore sketches and other stuff without a board in hand.

Hi,

Just to be clear: The section 8 "Root cause analysis" refers to:

Clock Misconfiguration / Bootloader Interference / USB Stack Failure

but how could it have been any of those, unless Arduino shipped it with the incorrect firmware or no firmware?

Is that the case, or is there something missing in the review (i.e. was the board firmware modified by you?). I think it's important to know, because all the rest of the review refers to a far more complicated method of working with that board, rather than using the Arduino IDE. I know you were fine using the more complicated method, but most users will expect (and want) to use the Arduino IDE with the Arduino board. Any clarification would be great. I would want to know, if I buy that board, will it come with the Arduino firmware installed or not (I likely will not care if I can re-upload it provided it's robust and not easily corrupted, but that for sure is good to know too, but that's a separate issue).

Shorting MD and SWDCLK does not seem right to me. It may work by accident though. MD is like BOOT0 on STM32s. Theare are two bootloaders on Arduino Nano R4. One is baked in the MCU and is triggered by MD pin at power up time. Second is Arduino bootloader is stored in flash memory and is triggered by two reset presses or whatever they use nowadays. It is not clear if "Unknown Device" come from Arduino bootloader (I guess) or Renesas baked bootloader which I would expect behave as standard USB DFU class. I think if you recover it by connecting MD pin to GND instead of SWDCLK, you were able to recover or flash new program directly over onboard USB using Renesas tooling without need of any soldering. But I do not have this board, so can't verify.

Yikes. I am about to fire up my Nano R4. I'll let you know if it fares better.

Very good post on your experience.

robogary — Sun, 29 Mar 2026 16:20:01 GMT

wow. So the short story of the Arduino Nano R4 that is was brain dead on arrival with no chance of recovery ? Was there any communication to the Arduino website or product service ?
