The big ecosystem of SBCs confuses me a bit. Who is buying these? The work required to build an actual secure, maintainable product on top of an SBC is so big that you'd surely never use one of these. The hard work is all in software. You need a supplier with product lifetime guarantees and a known SoC manufacturer. If you're a hobbyist, unless you really don't value your time you'd be much better served buying an x8…

So actually one of the thing that attracted me to the RV2 is the PCI Express slots. I was able to add a SATA controller and an NVMe drive to the same unit.

$40 is too expensive

It's pretty much the minimal cost for the form factor and accessories. It would be cool if they could make a $20 version with a lot less connectivity in a smaller form factor.

2 TOPS is not a lot for AI projects.

It's a lot for 40 USD. And not every AI project is a Language Model project.

no its not. Just use a smaller rockchip, 1-2 actual TOPS in ~$20 as a board or $10 a piece. i am using one for my project.

They get this number by simply adding up all CPUs' processing speed. There is no NPU or similar: https://medium.com/@zlodeibaal/orange-pi-rv2-ai-board-scam-7...

thats even worse. 0 TOPS!

The whole point is offloading load from CPU and doing something in parallel while NPU does its thing.

Don't buy an Orange Lie. I used to occasionally buy a single board computer ~10 to ~5 years ago. Then I waited until SBC's reached the 32GB RAM level. The first such affordable and performant board was an Orange Pi 5+ or 5B (I should double check, may add a comment later). I believe I wanted the Orange Pi 5+ but it was sold out, so I ordered and paid for the Orange Pi 5B (the 2 ethernet port variant) which was a bit…

What was the website you bought it from?

I caught Orange Pi doing misleading advertising earlier, trying to make people hear that the CPU has an NPU. Does this actually have any AI hardware or not?

Without mainline support, which it won't have soon, due to the lack of RVA23, this is just another trash product.

amazon.nl

EDIT: adding the seller on Amazon.nl was BestMii, and they were linked as the sellers from Orange Pi website.

Most of the SBCs are supported by fairly standard Linux distributions: Debian/Armbian or Fedora; you just boot from the approriate image on an SD card. Some SBCs have eMMC storage and/or a M2 connector, so you can either keep running off the SD card or transfer the image to that storage.

The value proposition of using SBCs is in their embedded connectivity; in addition to standard USB/network/HDMI ports they tend to have built-in connectors for:

* MIPI input, for video cameras

* MIPI output for LCD panels

* i2c and SPI for weird peripherals (accelerometers, temp sensors, etc)

* i2s for sound

* GPIO and timers/PWM for custom peripherals like motors/servos, contacts, programmable LEDs etc.

Anyone have openssl benchmarks? I.e. run "openssl speed" and post the output. Thanks!

I don't know if it uses the vector instructions. https://gist.github.com/faried/6955a992c6d68362fd1e07a1cd575...

Thanks! I'll compare it to my raspberry pi 4 when I get a chance.
