Or you can get a brand new N100 mini pc from Amazon for And for GPIO (if really needed) you can always add something like an USB Arduino micro (clone) for a couple of bucks.

I got one of these recently. It was ridiculously easy to just install stock debs on. Every time I look at the wall wart plug pack it comes with I laugh to myself. 8W. In terms of price, speed and compatibility the Raspberry Pi looks laughable. If I want GPIO I just use ESP32s with wifi. I am then unconstrained in terms of other stuff hanging off them. Using the new nano ESP32 boards I can just hot glue them to whatev…

Just for kicks, some reference:

Assuming the Gflops numbers are roughly comparable, ~50 Gflops would have you competing for the #1 spot in the first TOP500 list, June 1993:

https://www.top500.org/lists/top500/1993/06

Which came equipped with 1,024 SuperSPARCs @ 32 MHz:

https://www.top500.org/system/166997

Even ~2000, that might still have squeezed you into the bottom of the list? Note that power consumption of above system will have been in the 10s if not 100s of kW. To say nothing of size or purchase price.

That's only 1 human generation ago. What on Earth are you doing with these things? Running physics simulations of nuclear explosions, or what?

every person I know who has had problems with the Pis has had problems because they've cheaped out on either storage or power supply. the official power supplies (and others with the same ratings) are only sufficient if you don't plug anything into the USB port, don't have any hardware drawing power from the GPIO, and don't utilize Bluetooth and wifi 100% of the time at full throughput or anything. boot to a fast thu…

Oh no they are shit. And I used to design embedded systems years ago. I know exactly what I'm talking about. And you basically outlined it: they are bad quality and we have all these power problems and here's the insane list of workarounds . Incidentally I ran mine of an Agilent E3614A which was worth 30x the price of the Pi.

they aren't industrial embedded computers, so comparing them to some $1500 hardened industrial embedded platform is not only unfair, it's not a comparison that's respectful of the other participants in the conversation. you're relying on people not knowing about embedded hardware so that it appears your comparison is fair.

The Raspberry Pi is not an embedded platform in the ways that you are using for comparison. The Raspberry Pi is an educational platform.

They're all shit. Get a Lenovo mini PC off eBay and stick Debian on it. I replaced my shitty Pi with a Lenovo M600. If you want a dependable computer, stay away from pseudo-embedded hardware.

What’s the power consumption on that? The biggest draw for these machines (to me at least), is how they seem to run on a 5w power source.

power usage on a computer is not constant by any measure.

power usage spikes with CPU activity (among many other things) and if your power supply can't deliver the current that is required, voltage will drop, and things start failing, but only for 1ms or maybe even less. maybe even a single clock cycle in some cases.

if you can't keep the board powered fully for every clock cycle, then you are going to have problems, and that's true for any computer, not just the Pi.

Where do you buy an Orange Pi? When I was researching these devices I found it to be extremely weird/sketchy. These are three different websites all apparently from different companies: - https://orangepi.com/ - https://orangepi.net/ - http://www.orangepi.org (note: https does not work)

First two links are resellers, as mentioned in the footers. But yes, Orange Pis have always been a bit shady.

Orange Pi / Xunlong is a stable brand that's been primarily on Aliexpress for 7-8 years IIRC, producing various boards, all of which work fine for me. Very reliable seller, and the product + it's cheap. In the past they had Orange Pi PC, which was half the price of Raspberry Pi 2 or whatnot and much better in connectivity (4x real USB host interfaces, ...).

Their software I would not touch, but I never had to. Most Allwinner and Rockchip boards are well supported upstream. I just upstreamed support for Orange Pi 5 Plus a week ago or so.

https://xnux.eu/log/088.html

All you ever need with these random boards is to build your own Linux kernel and bootloader for them, which is a few fairly standard steps, and then you can use any normal aarch64 distro on them, even if the board is not "supported" by the distro.

I just have a script to cross-build the recent kernel for the boards I own, and update it remotely. Not a huge issue.

No they don't. I have a Dell Optiplex 3070 SFF (not even ultra small form factor, it is standard desktop sized) that idles at 8W. It has an i5-9500, 8GB memory, and a 128GB NVMe.

Various Orange Pi boards idle at 1-1.5W. The latest ones around 2.4W (not optimized, yet).

That $4 dev board looks like it might be an esp32 killer, or at least good competition. I was thinking of the esp32-c3 which is also risc-v with wifi and ble. It currently has really great rust support. You can even build the stdlib for it so you don't have to mess with no_std. The bl602 doesn't seem to have rust support yet, but I'm looking forward to more options.

> I was thinking of the esp32-c3 which is also risc-v with wifi and ble. I have a couple of the Pine64 boards that run Linux. Unless something changed, it doesn't have WiFi or BLE support, and likely never will. > The bl602 doesn't seem to have rust support yet, but I'm looking forward to more options. I think it does: https://github.com/bouffalolab/bl-pac/tree/main/bl808

Thanks! It wasn't on the awsome rust embedded github yet, but when I dig in I found it. The bl602 does support wifi, but only 2.4 and I presume at lower rates. It definitely doesn't run linux though. But I wouldn't put it past someone to figure out a way.

That's not totally true. I have a Dell Optiplex mini-PC version (and not that new) and it draws on average 10W, which is surely more than a RPi4 but not 10 times.

Farily comparable RK3399 idles at 1.1W.

You'd need to limit the CPU operating points or offline most of the CPU cores to get lower max power consumption under load. 5W is too strict for Orange Pi 5 Plus. And of course forget nvme if you want predictable low power consumption. nvme alone is 5-10W load. The board itself can run under 5W, but you'd have to carefully consider what peripherals you can use and how.

Arduino or similar over USB.

This is, in almost every respect, the better way. Any non-real-time operating system will eventually get a little bit buggy around timing intensive operations like I2C or (especially) SPI. Better to have your GPIO operations performed by a dedicated micro that only handles your serial traffic and whatever pin-twiddling operations you need to do. Ideally, your serial traffic is in a binary protocol like MODBUS-RTU, so…

Sounds like this would be very annoying compared to a SBC. You have typically several SPI, UART, I2C, gpio interfaces on the pin header on usual ARM SBCs. Ready to use from Linux via standard API, using DMA, etc.

Ignoring that the article is just an ad for his store, the thing that shocked me was the Orange Pi 5 Plus which includes "onboard microphone". I would NEVER want an onboard microphone unless it was a device I had far more than average trust in. What a great way to reward security breaches!

I think you hit the nail on the head. I completely aggree with you. You'd need something advanced like https://en.wikipedia.org/wiki/Pliers#/media/File:Long-nosePl... to even be able to remove the mic. It's impossible. Don't reward those hackers!
