content: In a press release, Qualcomm mentioned that Arduino would become an “independent” subsidiary.Yeah, right. Color me skeptical.Arduino will cease to be independent, when the Qualcomm C-suite dictates to Arduino to meet EBDITA levels which are aligned with the corporate expectations. If the Arduino guys can’t, they will then receive the “assistance” from corporate black belts that will be focused on “extracting value”.It is all downhill from there.

content: The only hope is that Arduino is so insignificant compared to Qualcomm's overall cash flow that they are not the largest optimization target.At the same time, they will obviously be inclined to use Qualcomm devices, which are proprietary as hell, so this is not going to work. There is no chance of them becoming mass market products. The same way as Renesas giving them $10M to put their MCU into the next board did not result in a good product.Qualcomm is also a huge patent troll, so I don't see that being accepted well by a large community. And I'd be interested in seeing what they do about all the clones. They might clamp that down too.

content: While a lot of random people buy clones, a lot of education programs are based on Arduino, and they typically buy real devices in bulk.This is the play here - get in early and make future engineers hooked on your devices. The only issue is that is works when your devices are not some undocumented crap that requires NDAs. But management is typically too delusional to see that.At the same time, a lot of educational stuff moved to Pi Pico, so not a huge loss.

content: Quote from: ataradov on October 07, 2025, 03:52:23 pmHow weird. The whole Arduino was supposed to be an example ofopen source hardware. That's also one of its educationalpoints. It would be weird if educators have trouble sourcing a "clone" - made from those same open-source design files, as originally intended by the Arduino folks.So in case of Arduinos, clones are not only legal, they arethe whole point.I could imagine that if the new owner for some reason kills the milking cow and stops manufacturing the boards, then surely some others will fill that void and start manufacturing and selling them with some more appealing premises (maybe their own branding) than random Aliexpress shop. That should be trivial, if there is need.

content: They don't have troubles, they are just not that price sensitive and they can get guaranteed quality from the vendor.I never said that clones were illegal. But given that Qualcomm runs the show now, they very well may become illegal, or require some aggressive agreement to be legal. This is how Qualcomm operates, they can't do it any other way even if they wanted to.Even Microchip constantly struggled with this. They've got this huge captive community handed to them, and all they could think about is how they can monetize that directly.

content: They are not interested in maker community, but they are interested in selling their "AI" garbage because if it does not sell, stock price drops.That board is closer to Raspberry Pi than anything Arduino ever did. And it might be a reasonable replacement for some RPis, but the interfaces on the board suck. It would be way better if they just made a cheap SBC under their own name. For $45 I would get one to play with.

content: Qualcomm is creating a commercialization path for students, getting their Dragonwing in the hands of engineering students is probably not the worst business decision.The downside is losing the distinction between embedded processors and lightweight computing. Most here are astute enough to understand the benefits of not running an OS when you don't need an OS but I doubt that's true in education or non-professional maker circles.Qualcomm's first product is UNO Q, an SBC running Debian, seems to indicate Arduino was acquired primarily for name recognition.

But addons from people or companies making peripheral devices may not be affected. Unless they see ecosystem die, so it becomes pointless to maintain them.But Qualcomm likely does not care, they have enough resources to throw at this if they wanted. But I really don't see them going forward with ATmega stuff for much longer.

They only value it as far as they can exploit it.Even Arduino struggled to get past the original ATmega board. All the new board they released never took off.This monstrosity has no chance. Why even bother with STM32? Just make a decent integrated SBC, and it will have a place and won't need an awkward IDE.

content: They will wreck Arduino, for sure. But it will not do anything to to AVR or PIC.Rising prices on classic boards will not accomplish anything. There is simply no money that would be meaningful to Qualcomm that you can extract from Arduino selling legacy boards.RPi can increase prices, but even them can only do that so much. There is minimal, but still competition out there. I personally use Orange PI for SBCs. They are cheaper, and in many ways better.But for Arduino there are dozens of compatible boards. Any price increase will simply move more people toward them. The only thing they can do is make IDE harder to access (hide behind subscription or even registration).They clearly want to push their new hardware, but they are going about it in a really weird way, which is destined to fail. I would expect this whole UNO Q board to fizzle out.

content: QuoteI agree that the Arduino hardware (and core firmware) are not very "actively maintained."The IDE gets more attention, and particularly its support of 3rd party boards and libraries is pretty close to "best in class" (except that it's not a "class" that attracts many competitors.) Like linux, Arduino support has been a gateway for various hardware/chip vendors to attract customers. ("It runs Arduino" is for microcontrollers very much what "it runs linux" was/is for SoC Application Processors.) (notwithstanding that sometimes such support is ... not very good.)And their forum is pretty much brilliant and brilliantly maintained. My favorite, somewhat above here, and FAR better than most chip vendors' forums.Qualcom could do a lot of damage in these areas. :-(

content: Quote from: floobydust on October 07, 2025, 06:04:41 pmAlso the dual chips and split ISAs is likely to be a pain. How is the communications between them? And $44. Ow.The Milk-C Duo series (CV1800B/SG200x) offers one Linux core and one microcontroller core with the same fundamental ISA (64 bit RISC-V). The Duo's microcontroller core is even supported in the Arduino IDE. For $5 (64 MB RAM) to $10 (512 MB RAM).Also everything with a SiFive "quad core" setup (JH7110 in VisionFive 2, the new $19.90 VisionFive 2 Lite, Milk-V Mars, Orange Pi RV, PIC64GX, PolarFire SoC (e.g. BeagleV Fire)) actually has a 5th 64 bit microcontroller core as well which I believe is normally simply unused. It should be possible to do Arduino support for it, I just don't think anyone actually has.The above things don't have an Uno-compatible GPIO connector layout -- they're usually more like a Pi or Pi Pico -- but I'm not sure that's a huge obstacle. I've built a few Uno shields myself (using Freetronics protoboardshttps://www.freetronics.com.au/collections/all-products/products/protoshield-basic) but I've never bought any.

A nice retirement isn't free.As a retailer I ended up giving away my last Yun boards. I might have an industrial Yun laying around here somewhere. I wonder how these new boards will fare in the market?I haven't seen any R4s doing anything interesting. My university still uses R3 clones as they're cheap and surprisingly hardy when in the hands of beginners.Hopefully Arduino can market these things appropriately. I'm sure YouTube will be full of click-baity videos in the next week calling it the Raspberry Pi Killer or one-sided bogus comparisons or how bad it is then ending up being happy with it or somesuch.

content: Maybe Qualcomm plan is to manufacture small/cheap AI accelerator chips, and make them become (for AI chips) what ATmega family was for microcontrollers. So, to take the concept of microcontrollers (all included in a single chip), and make it AI driven. Instead of blinking LEDs with a microcontroller, one would blink them with AI.Not only that you won't need to know all the technical details, but you can simply ask the AI to blink the LED for you.Sure, for today maker's standards, that will also kill all the fun, but who knows. Same as one can enjoy blinking a LED without having to write a C compiler from scratch, same one might enjoy blinking the LED by simply telling an AI to blink that LED.Eventually, Qualcomm can sell all kinds of online subscriptions, so to augment the local/onboard Arduino AI accelerators with extra features that will require cloud processing.

content: Quote from: westfw on October 08, 2025, 08:38:36 amNot *much* different. On an AVR I think it's around 3-4µs on a 16 MHz AVR no matter which pin. Maybe there's a couple more µs variation.On Linux it's probably mostly in the same kind of range on a CPU with far higher MHz, but then you'll occasionally see a ms or 10ms instead.That never happens on Arduino. At least unless you install some interrupt handler yourself. But then you can calculate (or experimentally determine) a pretty tight bound on the execution time of that too.

But even the newer boards with ATMEGA4809 in TQFP-32 (0.8mm pitch) should be OK.And there are TONS of variants that use the Arduino ecosystem, either through Arduino IDE or PlatformIO. From 8-pin ATTINY to 200+ pin BGA STM32H7s.Qualcomm seems so far from home in all of this. I haven't seen any of their chips live in the hobby/maker space ever.I surely hope they don't shitcan all of the relatively recent cool Arduino boards (like Portenta or MKR series) because they don't have Qualcomm parts on them..

The CPU they have here is decent, so if they just make a good SBC from it and sell that alone for $45, it would have a place. But actually make a real SBC with a real set of interfaces. No Arduino needed.Arduino community is great, but only for MCU-based boards. If they expect that community would pick up that Linux based device, then they are mistaken. Arduino community never picked up anything outside of the mainstream boards.This approach ruins two things at once. You end up with something that does not fit Arduino ecosystem at all, and you also end up with half-assed SBC.

As others have said, they don't care about hobbyists. What they care about is to promote Qualcomm via universities, which they are probably targetting here.So that'll be those SoCs with integrated NPUs running Linux and connected to some MCU externally. Meaning systems that will take seconds, if not tens of seconds, to start, and "abstracting" hardware even more than it was already with the Arduino frameworks.I don't give this venture much time either before it's dismantled, maybe a couple years at best. Then they are likely to resell it to Softbank.Rinse and repeat.And if they don't release documentation of their SoCs (at least the ones they'll use for this platform) to the public, that'll achieve no traction in terms of support and you'll just get what Qualcomm will give you, probably all pretty well obfuscated. The RPi have used Broadcom SoCs for ages now and official documentation was never publicly released, so don't expect anything else here.

The Arduino Q is too advanced for that level.I just hope they keep the traditional small boards, which are the core of the Arduino world.For 32-bit powerful boards, we already have the Raspberry Pi and similar devices.

Both chips are pretty good, to be fair. It doesn't look like anything that the average Arduino user would go for, though.

Typically you could buy the Arduino boards always because they were sold at 500-1000% markup, it was good for the hardware selling business.The raspberry pi guys really must have pissed them off, when they started selling boards for 4 bucks, when the comparable Arduino micro is 25.QuoteI bet you could make a board with only the STM32U585 that would fit perfectly into the Arudino ecosystem.So I agree with the ppl here, bad move. I can smell the "synergy" from a kilometer that was the sales pitch.Quote from: Marco on October 08, 2025, 09:12:28 amI don't see how this would sell their IC. I searched for the QRB2210. Arrow has it listed, 0 stock, RFQ, MOQ is 168pcs. Nobody who uses Arduinos will design with this IC. Literally nobody. You need a hundred bypassing capacitor and DDR memory length matching to make it work. Instead of a DIP package and maybe a capacitor somewhere.And Qualcomm actually has some interesting ICs that would fit on this board. They have chipsets for BLE headsets, that have a Cortex M33 or similar core, 80 MHz. Only it's usually a smaller package. But they can offer it in a different package, disable BLE, and have a microcontroller ready with relatively small amount of work and time.Quote from: EEVblog on October 08, 2025, 05:04:22 amI would say the only real value is their github repo, where you can pull a library that works most of the time.

Especially if they can design it into a form factor/schematic that utilizes its low power features.Looking at other announced Qualcomm SBC boards, they all look like advertisements for Qualcomm instead. Shoving SBC onto the Uno form factor without any I/O and hiding a STM32 on the back side is the stupidest idea I ever saw in the maker space, and I think that triumphs a lot of stupid ideas [/cynicism level lowered]

content: I don't know, there is a list of boards supporting hardware debugging, random search result:https://www.slashgear.com/1595272/which-arduino-boards-support-debugging/That blog post is from 2024. Did Arduino removed the debugger from the Arduino IDE in the last year?

content: The link that I've posted is about hardware debugging, those boards do not use a software stab, that is my understanding from the link posted above.Anyway, I won't insist, since I don't use Arduino IDE 2. When I really need hardware debugging for Arduino boards (like Arduino nano or Arduino UNO (based on ATmega328 AVR), I use the Debug-Wire feature of that microcontroller, but I'm using Eclipse instead of Arduino IDE. Works even for smaller AVR chips, this is a printscreen for hardware debugging an ATtiny13 using Linux + Eclipse + dwdebug + AVR-GDB + debug-wire, and a generic USB to serial with CH340 + a diode as the debugging probe:printscreen fromhttps://www.eevblog.com/forum/microcontrollers/avr-(arduino)-linux-debug/msg3511900/#msg3511900

If that fails, she gets gruesomely ripped apart for whatever parts are still good. Luckily, the community, recognizing what was going to happen, had made a clone of her (possible thanks to open source), so forget all the horrible things that happened and just learn to love again. Wait, did I just describe Microsoft Windows 10/11 and WSL?
