For me, Pi6 shall focus on NPU to run edge models instead of getting into minipc space, e.g. 10TOPS built-in, that will be slightly better than Rockchip 3588 which was produced 4 years back at 6TOPS, and way more powerful than NXP's 2TOPS. 10TOPS is the sweet spot for edge AI as far as I can tell.

Designing a chip for one person is doomed to fail as a business.

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.

It's not $0.50 extra. It's $0.16 extra for a USB-C port assuming you bought the USB-C port on mouser at 10k quantities and threw the micro USB port away.

I just don't get it. Anyone who wants to save a few pennies just buys the chip directly. Their Pico board is primarily for prototyping and one off products, where quality of life is everything and 16 cents is nothing. The adapter cable probably costs more than the amount they saved. That's a dick move.

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 ( 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 sur…

I'm on a phone that makes it a pain in the ass to switch languages. Do it yourself.

I cannot fathom why USB-C would make any difference. It's not like USB-C is intrinsically better for this use case? If you're doing hardware development, your desk is likely full of in-development crap anyway and a micro USB cable more or less won't make any difference whatsoever, nor is the Pico likely to the only thing needing a micro USB cable. Edit: one thing I can think of where micro USB connectors are better:…

USB-C is a better connector in every aspect. Micro USB is a terrible connector. It's that simple.

The economics don't add up either, because an adapter cable costs money too.

I wonder how they are positioned now in the market. During covid I wanted a small low power always on server. I thought about Raspi, but at the time it was expensive and I went with an intel nuc, for a similar price. Now if I wanted to do hobby electronics, I heard I should look into esp32 or stm32..

I use a Pi 4B as a 24/7 home server in a country where domestic electricity is expensive (and worsening).

Each Pi release is more powerful, but uses more energy. I found the Pi 4B to be the sweet spot for me, because it is the earliest model to support USB booting, gigabit Ethernet, and offer > 1GB RAM.

Perhaps a used one would fit your purposes and budget?

I currently use it to run PiHole, serve media via SMB, host Postgres & Redis, and run some custom written Dockerized apps. Home Assistant to possibly follow, too. The current load seems reasonable in htop, but I haven’t looked into burst scenarios.

We need a 5 lite. The specs of the 5 without the massive power draw and heat generation

Earlier quoted context omitted.

> with their out of tree drivers rephrase please?

They’ve got external kernel modules that they use for some hardware that is not supported upstream, namely the GPU, but also some things like Ethernet I think. Everything else is upstream though, so the situation is similar to a regular NVIDIA GPU. Who would’ve thought that NVIDIA started upstreaming stuff once they realized how much money Linux is making them?

ahhh, it's out-of-tree as in one word

I thought it was "out of three" or something

human parser error :/

It used to be that raspberry pi was a cheap pc. Well it's not longer cheap. And at their price point, you could just get a mini PC and have better performance, or if you want to use it as a microcontroller, you can just use an arduino, esp32, or an actual microcontroller for a fraction of the price and power consumption. So, what do people actually do with these pies?

I've got one set aside to play with v4l2m2m. Once that's working, it should improve video encoding support in my OSS project (https://github.com/mickael-kerjean/filestash)

More than one person is buying Rockchip powered systems. A new high-end RPi has to at least match the hardware features of a RK3588 or RK3688.
