What is your take on Qualcomm Arduino becoming Persona Non Grata

Must be one of the biggest myths out there that Arduino is just for hobbyists. Arduino are simply doing what any good sound commercial business would do. Nothing wrong with that at all. They continue to innovate and, in my opinion, the Arduino Uno Q is very innovative.

Qualcomm are also being very proactive too with the launch of some new dev boards themselves. E.g. This series looks very impressive.

So no, certainly not Persona Non Grata in my book. 

More then 200 people is interested in getting Ventuno and revieweing it here on Element14, so I would say it is quite popular: Ventuno Q RoadTest. In fact it is the most popular device we have seen there in at least last 5 years.

At the same time stocks at distributors are mostly full and it is questionable if Uno Q sells well? To me it seems that many hobbyyists are interested in free Uno Q (like Hackster gave 300 units as part of some competition, E14/Farnell also gave them away in high quanties in various competitions compared to other HW). But I am not sure how many free Uno Q recipients made something production grade with it and bought actual units afterwards. (My personal score: 3 free units, 0 bought )

Arduino started off as a platform to make it easy for people to get started with electronics and they did an amazing job at promoting the ecosystem. There was a board for every level of expertise, all levels of pricing from cheap to expensive. What Qualcomm tried to do apart from the legal chaos in their Terms of Use/Service is try to push a product that not everyone wanted. Arduino Q and Ventuno is something of value to people who needs a combination of Linux and Real-time controller, and to get on the AI bandwagon. Till now People used a Normal SBC (RPi/Jetson etc) along with a microcontroller to get the things done, so on the specs side, it was tempting to have a board with both the MPU and MCU with good hardware integration. But The problem became actual usage. For simple / fusion AI based on sensor reading We do not need SBC. It is usable when we need Lidar/Camera. But Arduino Q does not have physical ports to connect them. Which means I need the expansion board or an USB-C Hub. So instead of a SBC and MCU Board wired together, I am seeing Q, USB Hub wired together. I am losing the freedom of choosing the combination of SBC and MCU in exchange for a good looking board. Usability wise, I give it a thumbs down. 

misaz mentioned people are interested in Ventuno for reviewing. 300 Units of Q had been given away, 2~3 Design challenges in our community itself had  Arduino Q in their Kits, so on the surface it looks like there are interest, but the question is are people putting their own money to buy the same board? Of course there can be really good use-cases for the Q and Ventuno. I am looking at making one as Home assistant and another to run Klipper, they are all experiments.

I would not say the boards are persona non-Grata but Qualcomm current strategy/philosophy definitely is.

Here's a real experts opinion on the Arduino Uno Q.

As the author notes: "Why build a board this way? Because the two halves are bad at each other's jobs, and every serious embedded Linux project eventually rediscovers this. Linux gives you Python, OpenCV, TensorFlow-class models, filesystems, and Wi-Fi, but it cannot promise that your code runs in a deterministic manner: a garbage collection pause or a busy scheduler between you and a stepper motor is how projects fail. A microcontroller keeps promises measured in microseconds but would spend all its RAM opening one HTTPS connection. The classic RPi answer is two boards and a USB or uart cable; the UNO Q's answer is one board where the pairing is designed, powered, and (the actually novel part) programmed as a single unit."

A sample size of 200 seems pretty insignificant to me to measure popularity. 

I hadnt been able to score a free one so my on hand inventory remains 0. 

I have several RPis already and the Arduino Q is like a RPi with a built in Arduino with no easy way for them to share a register table. 

I think it will become popular once a lot of application is build around that platform and there is a high demand for those application.

I'm fine with everything but there are a few questions that comes to my mind when it comes to software part of the boards like Uno Q.

Right now, there is support of software from Arduino or maybe Zephyr (I have not tried this) for communication between these two MPU <--> MCU over RPC and hopefully they will add more functionality like this in the future. But then one is fixed to use specific RTOS/software to make full use of the board until some open-source people come and contribute their code enough so that both devices can talk to each other. So sometimes we are forced to use a specific software that may be a bad idea. !

Also, some people have said above that the road test for Arduino has reached some 200+ applications. That shows how much "Popular" it is. That necessarily do not reflect that every other working product has Arduino in it. Because it is more popular and comparatively easy to use, people know it well and people apply to get it. If there would be some FPGA board from Xilinx, then a lot of people would not apply because they do not have skills or sometimes interest in FPGA that much. I would say Arduino is more versatile for embedded systems. 

Also, for example, hacksters and other platforms gave some 300+ Uno Q for free. I appreciate but then some people have more than one Uno Q and some even have five.! Insteady, they could have given Media hat for Uno Q to try out the dual camera and mic setup. 

my personal understanding is also that Arduino's advanced boards such as from Pro series had some issues. For example, there was lack of software support for some peripherals etc, etc. And Qualcomm now can make is better. Cause Arduino has released a lot of boards even they have made FPGA based boards. such as MKR Vidor. They might be struggling to manage a lot of different chip vendors and their software.  

I'm switching all my small projects over to Seeed Studio XIAO boards.  I certainly can't afford to purchase a bunch of Ventuno boards.

I do a lot of small projects that require I2C, SPI, and a few GPIO, plus maybe a radio.  I almost exclusively use XIAO boards for those.  I use Arduino and RPi MCUs a lot less than I used to.  The ability to have a huge choice of different MCUs in the same small footprint is great and many of the boards are really low cost (under $10).

I think the Uno Q and Ventuno Q may be a good fit for larger projects, but it will take some time to see if they will work for me.  I’ve tended to use RPis in that space.

They do look interesting but one question that I could not answer from their product page is what tools do they use to get programmed?

I mean, I do almost all this kind of development inside VSCode with mostly PlatformIO but it wasn't clear if that's the one to use.
