Raspberry Pi Holdings is a embedded systems manufacturer for pity's sake; we don't need more from them, we need less. [EDIT] A faster Raspberry Pi 6 is encroaching on the territory of the Intel N150 and its successors and mainstream Linux distributions and that is a battle they would lose in terms of price and performance.
Give us a Raspberry Pi Zero 3W with proper sleep states to reduce sleep power consumption, lower idle power while awake, and 1 GB of RAM even if it doubles the price.

I agree that Raspberry Pi is not a good general purpose computer, but some of these criticisms are starting to feel like a pile-on with partially incorrect information.
> the latest pi needs considerations of cooling solutions
FYI you can run the Raspberry Pi 5 without a fan or even a heatsink. It will safely throttle itself if it gets too hot.
If you're trying to get maximum performance out of it all the time, you will want a heatsink and fan. If you want to run some Python scripts in a Linux environment or even if you're doing heavy work and waiting longer is not a problem, you don't need extra cooling.
> and a beefy power supply (no more just any old micro usb cable into any old usb port)
This hasn't been true in 10 years.
Powering something off of any old USB port means it would have to fit within the 5V 500mA basic specification, which the Raspberry Pi 3 exceeded long ago.
> It was a "microcontroller" you could program in Python
It was never a microcontroller by any definition of the word.
> It was a "microcontroller" you could program in Python with a friendly Linux environment and is now an expensive, power hungry, hot computer with a microcontroller hanging off of it
The Pi project was never originally a microcontroller - it was always a full-blown SBC you could program any way you want with some GPIO pins attached. People literally used them as (slow) home computers.
The company didn't sell its first microcontroller until years later in 2021 with the Pico, by which point we already had Pi 4. I do though think its a real shame prices for the SBCs have risen as they have.
On the other hand, the RP2350 actually is a microcontroller, and IMO a nice one for many purposes. PIO, high-quality datasheet, nice ecosystem, etc. And the Pi Zero 2(W) can do most things the Pi/Pi 2 could, with a smaller footprint and less power consumption. Variety is nice.
Do you have a reference for this? Looking around, I see it being beaten by other ARM SBCs, and even low end Intel devices.
Many years ago, I measured performance per watt of the original Raspberry Pi when they were still relatively new. The performance per watt lagged behind even a beefy Intel box since the original Raspi was so slow that it destroyed any gain it got from using so little power.
They've never been particularly low-power, in a performance-per-Watt sort of way compared to other offerings at whatever present day. In recent times, I've seen completely-believable reports that N150 boxes walk all over it.
They've never been particularly cheap, in a performance-per-dollar sort of way. Used machines from eBay, yard sales, and old broken laptops (that still compute!) have always been better. (They usually come out OK when new is compared to new, though, which is IMHO the only valid comparison.)
Those comparisons were never very favorable.

The parts where it shines are: Small; they come in two sizes, and those sizes are small and smaller. That was new, but it's been cloned all over the place.
Built-in GPIO that's meant for people to actually-use and tinker with. That was new, too, but it's also been cloned. (Also: These days, anyone can plug a cheap Pi Pico into any PC with USB and get a fairly intense amount of GPIO to goof with.)
Standardization, and the appliance-like behavior this can enable. Lots of folks, including kids of all ages, just download pre-built images and swap SD cards like they would cartridges in a Nintendo. That's not for me, but it's pretty neat.
Community. They've still got a lot of momentum by being first at these roles. That's good. It helps newbs (who at this point may have never had anything resembling a "real computer" to play with ever before in their lives) to get started.
Low-power enough: It's not ideal when chasing tiny Watts for battery or small solar power, but you probably won't notice it on an electric bill (and despite the bizarro-world cooling rigs people put together, a passive heatsink really is good enough to keep it running in-spec).
raspberry pi has terrible power management as well. turning off a core was impossible on previous generations for example. a few years ago rpi was the worst of all sbcs we measured for battery powered usages. this was for an actual embedded product so it wasn’t going to be used either way (ask broadcom for some chips HAHA)
but there is very little reason to use a rpi over other sbcs if you have a remote idea what you’re doing beyond hobby use
Maybe a tick-tock release cycle (one with new features and some speed, the next with the ~same features and more speed) is where they're headed, and maybe that makes sense. They wouldn't be the first.
I'd love to see even-lower-RAM versions, though. Most of what I use Raspberry Pis for at home for is not RAM-hungry at all.
My Pi4 network router has 2GB because that was the smallest/cheapest version at release when I got it, but the system itself consistently only uses about 64MB of RAM. It'd do perfectly well and have a ton of breathing room with just 128MB of RAM (which will never happen, but if it did happen...).
I suspect the Pi4 that I use as a set-top box with Kodi would be fine with 512MB.
I've used Zero Ws for all kinds of things over the years and never felt RAM-starved with their little 512MB of RAM.
So I'm learning towards 512MB.
But sure: 1GB options would also be fine even if it does double the price. Our comments serve to demonstrate that there's room in the marketplace for different SKUs with different memory capacities. :)
I think exactly the opposite: we have no shortage of embedded crap we can buy; what is useful is dismembering intel. It would be better if the pi were risc v but this will do for now.
The 8GB Pi 5, at $170 [1], is encroaching on Jetson Orin Nano Super's $240 price point [2]. But the Jetson has a faster CPU (newer a78ae cores rather than a76) and, obviously, a whole-ass GPU.
Nvidia's software platform for the whole Jetson series was, at least in my experience, absolutely awful on the Jetson Nano and Orin boards I worked on. Has that improved at all? I did not appreciate that the only option they provided was a full desktop version of ancient Ubuntu... and even flashing the OS image was a bizarre process.
Edit: looks like they at least have a better headless option now.
Would love to see actual security focused hardware/software features, like full OP-TEE, fTPM (or a more ideally a real physical TPM), and similar. For example, so that the OTP isn't the only way to store a disk encryption unlock key.
The existing secure boot mechanisms aren't bad, but allowing for more than one public key hash in OTP would be nice, too.
These kinds of things are expected to be on modern embedded SOCs and SOMs now.
I have bought an rpi at every generation. And I still have yet to find an actual use for them.
Everything they do from a compute perspective is just better with a mini pc or old laptop with a mobile spec chip.
Everything they do from a programmability perspective is just better with a microcontroller specific to the task.
I just don't see the actual market position for these things. They were supposed to be a cheap board, but you can't actually buy them cheaply because the vendors upcharge so much.
> I have bought an rpi at every generation. And I still have yet to find an actual use for them.
It's amazing how well these fit into the category of products that people feel compelled to buy, play around with, and then forget about.
Flipper Zero is another product that landed in the same space.
What's sad is that Raspberry Pi does have a lot of legitimate use cases and people who want to use them, but the supply has always been swamped by all of the demand.
* Replacement controller for my UFO Catcher - It has WiFi, easy to update, and I can operate the machine remotely with it. It's bolted to the back of small touchscreen that lets me change the machine settings as well.
* Remote printer access - I can monitor from the USB cameras and gather statistics about the prints.(I suspect a lot of 3D printing enthusiasts use them for this purpose.)
Having a small low power computer has been useful for me in those instances.
I think at this point the brand reputation and software quality are a big selling point.
If you're trying to build a couple of units of some embedded thing where you need to toggle some GPIOs or serial devices in response to requests over the network, but don't have the expertise or resources to do it with a microcontroller, a Pi is a great option - you know you'll have software support, and you know that the vendor will be making the exact thing you bought for 5-10y.
For hobbyist stuff at home, I agree, though. A mini PC is probably better for homelab stuff, and an RP2350 or ESP32 is probably better for anything embedded or battery powered that you want to do.
Obviously the business model is selling a $30-100 SBC to jerks on Hacker News who simultaneously brag about buying literally every single model, but apparently have no use case for them. Even better, these schmucks will never plug the product in, never submit a warrantee, and never harass support. Brilliant model!
A very small point, but pulling from a feather form factor BOM to compare.
$0.12 for microUSB female connector (rated 1A)
$0.26 for a USB-C female (rated 3A). Needs 2 x resistors (< $0.01), 20% larger board area
I think the power capabilities are the biggest item. If you want to pull higher current from a laptop for development or supply from a wall, you have to switch to USB-C.
I don't think either of these prices are that aggressive - pretty sure the cost comes down at volume.
I wonder if it would be worthwhile for them to produce both. Well, it will be hard to compare because the design cost doesn’t show up in the BOM, haha.
But it seems like it would be useful nowadays, since some laptop have mostly USB-C connectors, and USB-C to USB-C is pretty common. I’ve never seen a C to Micro. Do they even exist?
I have an unfair bias because I design PCBs as a significant part of my job, and switching out to USB on this board appears to be a non-issue.
I have a Pico in front of me, and there's plenty of room there for a USB-C footprint and the two 5.1k resistors. Given that, I cannot reasonably agree that the "design" stage is significant.
In other words, it's a change that I would make to my own board in 2-5 minutes because the stakes are low. My ballpark guess is that such a change at RPi would have to go through a proposal stage, a PCB change review, and then there would be dozens of places to update documentation.
Since backwards compatibility is non-optional, this would result in a separate SKU, which means that the whole distribution chain needs to be updated with a new product.
So, I acknowledge that when you're working at their scale any change like this is the definition of non-trivial. What I don't agree with is the conclusion that it's not still clearly the right thing to do.
The only way I'll buy another raspberry pi is if they come with a power supply that's guaranteed to work with them. I got tired of the random reboots in the night and replaced my media center/NAS with an old Nuc.

And to the GP's point - the Pi Pico can be programmed in Micro Python.
Performance per Watt still outranks any other (quasi-)mainline linux device
Do you have a reference for this? Looking around, I see it being beaten by other ARM SBCs, and even low end Intel devices.
Many years ago, I measured performance per watt of the original Raspberry Pi when they were still relatively new. The performance per watt lagged behind even a beefy Intel box since the original Raspi was so slow that it destroyed any gain it got from using so little power.

You have issues.
Pi's refusal to drop a USB-C on Pico due to cost increases is a terrible call IMO.
I seriously cannot fathom being someone doing development who wouldn't pay $0.50 extra to purge the last micro USB from their desktop.
