Re: Tiny quad-core system-on-module for makers and hardware startups
#42I'd imagine it'd be competing directly with the likes of Raspberry Pi 3 Compute Modules. And the RPi3 CMs don't seem to be as popular as the RPi 0 so far. And that's given the RPi was super popular, and was known for their amazing community and commitment to connection standard, support and production. This is even more hardcore than the RPi 3 CMs, and more expensive. Seems like you have a brave team to tackle on thi…
True! I think that the reason why we do not perceive CM3 as popular is that it is not something that you can use right away. Unlike Pi Zero it requires a custom carrier board, which narrows customers to those who are trying to build a product with it. They normally do not share much online :) Neutis has advantages over CM3, it is much smaller, comes with Wi-Fi and BT and the connectors take much less space on the PCB…
Furthermore, the Pi Zero is single core and very hard to source in bulk for product integration.

The Orange and Nano Pis are not FCC-certified, so they're not likely to be integrated into any product sold in the United States, at least legally-speaking, assuming the manufacturer doesn't want to be fined. Orange pretends to be certified[1] (the PDF is named FCCCERTIFICATION), but it's mere verification (now called Supplier's Declaration of Conformity, or SDoC), and SDoC is not the same as certification[2]. If a m…
I can't speak to pretending or not, but at the bottom of this NanoPi/FriendlyElec page, there are very similar looking pdfs for fcc, rohs, and ce. http://www.friendlyarm.com/index.php?route=product/product&p...
Thank you. I couldn't find that with a Google site search[1]. But yes, that's not full certification.

ESP32 sounds like it meets your needs, but it won't run Linux. It will run MicroPython though.

Any linux board that has a USB A port, runs the bluez stack and node js, can do this with a $5 bluetooth dongle.
There's a really nice set of node.js libraries, noble and bleno, which allow you to communicate in both directions. Noble allows your linux box to be a central device, and bleno allows your linux box to be a peripheral.

Well, yes, the Raspberry Pi has much better upstream support. The biggest obvious issue being the Mali.
I mean upstream support in the Linux kernel. The Allwinner chip is supported by the mainline kernel, the one in the Raspberry Pi is not. To me that's a big plus in its favor. Also in terms of support by the creators, if they're serious about the 10 year commitment then I'd say actually that is better than Raspberry Pi. Mindshare in the maker community isn't that important to someone doing serious embedded hardware de…
No offence, but I think you haven't been keeping up-to-date. The RPi is fully supported by the mainline kernel, most significantly, there is a full atomic DRM kernel driver for the VC4 GPU and corresponding Mesa userland, maintained by someone with transistor-level access to hardware documentation.
I have great appreciation for the work Maxime Ripard et al. have been doing on mainline support for the various Allwinner chips, hence why I kicked in a few bucks for their kickstarter on reverse-engineering the Allwinner VPU:

But lets not kid ourselves, none of this was Allwinners doing and they could not give a fuck about mainline Linux.

#47It claims to run on mainline Linux but mainline Linux does not yet support CPUFreq, hardware crypto, HDMI, nor the GPU for the Allwinner H5.

I've always wondered where the line is on a product's FCC certification. Obviously US retailers such as Adafruit and Sparkfun have sold fully assembled unlicensed radio equipment for over a decade. What subtle changes could these companies make with their products that would suddenly gain the interest of the FCC?

Wow you're right, not sure how I missed that. Guess I just got too used to all those years of Broadcom chips being giant clusterfucks of patches and old kernels.

Do you have an example? SparkFun even has a blog entry about certification that's a useful read, although not entirely accurate.
