It doesn't seems unreasonable for them to want an email address before giving you PDFs of their stuff. They do want additional verification to get more detailed docs, but on the spectrum between available on the open Internet to all as a 1, vs only available on a hardwired line on a LAN on a military base at a 10, I'd give Qualcomm, I dunno, maybe 4?
In contrast, Microchip (and Atmel before it was acquired) made the datasheets for the MCUs used by Arduinos truly publicly available.
Basically everyone openly publishes their datasheets. It's normal and expected
Just because most of the free software ecosystem relies on unpaid volunteer work does not mean it is a desirable state of affairs, especially with billion dollar companies building on top of said work while hardly contributing anything back.
While that is true, if Espressif and the Raspberry Pi Foundation can build their SDKs and still offer cheap chips/boards, so could Arduino. I'm not expecting a $0 markup, but Arduino prices are simply unreasonable for what they offer, especially if you live in a lower income country.
If you think the price is unreasonable, don't buy. You have listed what you seem to think are better options. I agree that there are better options. If somebody else wants to spend their money in different ways than I do, let them. If Arduino thinks they can make money this way, let them try. If it works, good for them, I guess. If it fails, I guess the joke will be on Qualcomm. Honestly, Arduino could slash their price to be $1 less than a Milk-V Duo and I'd still by the Duo. If the Arduino was $1 less than an ESP32, I'd still by the ESP32. So I'm not sure lowering prices wouldn't just hurt them.
People are making so much of this when it seems so much simpler. Qualcomm likes buying high-margin businesses, and Arduino is a high-margin business. Gross margin on their boards is over 90% (hence why you can buy a Chinese clone of a $30 board for $3) and this trend shows no signs of slowing down. The TI equivalent of the $30 Arduino Uno is $5, and it's a true gateway product.
The Raspberry Pi Pico blows the Arduino out of the water in terms of computational speed, available RAM and so on, and it costs a fraction. I don't remember using an Arduino since the Pi Pico came out. And if the Pico isn't enough there are the bigger family members waiting in the wings. For me Arduino is mostly over. And then there is Espressif as well, they make some neat boards.
The problem is that there just isn't a whole lot of money to be made in providing hobby hardware for enthusiasts. Every time a big player gets involved, they think they can change this. A decade ago, Intel tried that back in the day with Galileo / Edison, and tellingly, they came up with the same "ideas": IoT / AI. If you're doing cheap IoT trinkets, you're never going to pay extra for a brand. You're going to buy th…
A competent engineer designing a devkit as simple as an arduino needs about 1 day of work. Give it a week to include debugging. Amortize that cost over a million units and engineering time comes out to less than one cent per board.
It’s not quite that easy, and besides the hard part is the SW. arduino spent years writing SW code and still does to make it easy to run, debug issues and provide support. Also a million dev kits is unrealistic for vast majority of companies 5-20k is more the number I hard.
To be frank, the Arduino ide was a fork of Processing's and the compiler suite was GCC. They 'simply' glued the pre-existing pieces together. I'm not saying that it's trivial to do that but it's also not exactly a herculean task. Even the bootloader was a fork of Hernando Barragán's pre-existing Wiring project.

Long live Teensy [1]! I just wanted that someone mentioned these Arduino-likes in the comments. I suspect many of you have come across them though. [1] https://www.pjrc.com/teensy/
The teensy is so weird though. At least back when I played with them. They put a secondary chip which let's you flash over USB but they cover the debug pins and the only way to get serial over the USB port is to have a whole USB stack as part of your application. As a development board I would rather go with one of those STM32 backed boards and a knock off STLink, you need the STLink to flash, if you want DFU you can add that yourself, and you get a debug adapter.
If they've done 500k units, "based on a respun Uno" almost certainly means "there's a atmega328p on the PCB, a 16MHz crystal, and some points granting access to the serial and reset pins"
ATMega328p, 32768Hz xtal, in a smart radiator valve. See OpenTRV (for the open part of the s/w and h/w) and Radbot for the commercial product.
That's a cool product! I wish I could put something like that on my hydronic (hot water) radiators, but they don't have individual valves.

Yes, the Teensy is pretty impressive too. I've used one in a project and came away impressed.
Don't look at just the specs. You also need to look at the board design and programming environment. I've used the ESP32 native tools and they are a lot more complex than Arduino. But I'm an embedded firmware developer, so it's kind of what I expect. But I used an Arduino, with 5V tolerant outputs, to light up Halloween costumes for years. I do it in 1 page of code that's I write in their IDE. I don't have to set up…
> I've used the ESP32 native tools and they are a lot more complex than Arduino. How so? All of that is abstracted away from the users just like it is for Arduinos. In fact you can use the Arduino IDE to develop for most ESP32 chips. If anything Arduino is holding back everyone with their horrible IDE. Their Board and Library managers are painfully slow and having no way to store configuration with your sketch means…
It's not just backward compatibility -- USB as a convenient source of +5V is going to be around for a long time.
Yeah, I just did a project at work with an RP2040 and was really impressed with the Pico SDK. It hits a sweet spot in between ST’s insanity and Arduino’s easy-but-not-powerful tradeoff. No crazy code generation, going from 0 to blinky is quick, but also going from blinky to DMA’s and interrupts is also a breeze. I will say that I think the hardware peripherals in STM32’s are miles ahead, and PIO’s don’t necessarily m…
Yep the STM32 has certain advantages, even if they are usually complicated to program. With the Flipper Zero I programmed a low level timer interrupt and had to setup don't know how many registers... And the documentation is lacking. Also I love the fact that the STM32 comes in 5v variants that are great to interface it directly with things like a Commodore 64 or a Spectrum.
