> "The GR8 seems to be a rebadged Allwinner chip" It could be, but reading up on the features of the C.H.I.P. Pro it supports mainline Linux. I assumed this meant without blobs. Is there mainline support for any Allwinner chips?

Many A20 features are in mainline kernels now, although sunxi-3.4 is still recommended for full hardware support. http://linux-sunxi.org/Linux_mainlining_effort#Status_Matrix EDIT: The GR8 is specifically called out on this page as having mainline support from kernel 4.9.

Sadly Allwinner did zero of that mainlining.

What's with the "no NDA required"? Who requires NDAs for their datasheets?

Many companies. Almost too many to list. This is probably a dig at Broadcom who makes the chip in the Raspberry Pi and usually requires NDAs for their chips. Hell, Broadcom won't even let you buy many of their chips without their permission!

OTOH Broadcom is paying someone to write open source 3D drivers for the chip in the RPi:

Hoping to put this or RPi3 into foldable card cases and connect to power, vga/lcd monitor, keyboard and mouse for schools in developing world. Would the chip or chip pro be better than RPi3 please?

Great hardware, but do you really want to run a full Linux system on low-end IoT devices? That's what made the recent massive DDOS attack possible - lots of little machines with way too much network-side functionality. Linux just has too much attack surface.

Its not Linux that was being attacked, it was the apps that were running. From https://blog.cloudflare.com/say-cheese-a-snapshot-of-the-mas... > While it's not possible for us to investigate all the attacking devices, it is fair to say that these attacks came from Internet-of-Things (IoT) category of devices. > There are multiple hints confirming this theory. First, all of the attacking devices have port 23 (telnet)…

Exactly. The best-selling home IP camera on Amazon [1], from a Chinese company, has the following "features":

- Default Wifi setup is done through their phone app through the "cloud" (let me tell you how much I trust that one)

- Has a webserver listening on port 80 with default u:p admin:admin (to be fair, their instructions are clear that you should change it, but it's not a mandatory part of the setup process)

- Has an RTSP server listening on port 554

- All of this a disaster waiting to happen because of UPnP (ugh, how many home routers have this enabled...)

- Sends outbound TCP traffic to amcrestcloud.com and amcrestview.com every few seconds (cannot be disabled on the device) [2]

- Sends a continuous stream of UDP data to 52.91.189.219:8800 (cannot be disabled on the device) [2]

The only way to prevent this device from a calling a CNC server is with a hardware firewall or an isolated LAN segment (I suppose this idea isn't at all specific to this camera). I bet fewer than 0.01% of their customers do that.

There's a post[1] on their forum for more detail. TL;DR they are announce 2 new hardware

* GR8 - a 14mm x 14mm System-in-Package, combines 1GHz R8 SoC with 256MB of DDR3 memory - $6 - available in any quantity in December 2016

* C.H.I.P. Pro - GR8 + 512MB NAND + WiFi/BT + ..., 76% smaller than C.H.I.P. - $16 - available in volume December 2016 and Dev Kits are on sale today for $49 shipping in December 2016

Having some hobby project with CHIP and loving it, but I have to say this naming of Pro sounds misleading, I'd rather call it Air :)

Is it possible to make use this as a starting point for an open source smartphone?

In theory, yes, but the lack of LVDS/MIPI display connector/driver (or even HDMI) makes it difficult to connect any practical display on it.

What are the LCD-Dx lines for?

I have the chip, esp8266, rpi, teensies, trinkets, arduinos... I studied electronics principles and built various circuits.. yet I have no idea what I can practically use these devices for in my life. They all sit in a box and I have a hard time justifying buying more of them.

Set up an automated indoor garden. I'm currently working on a simple ebb and flow hydroponics garden with a dashboard to monitor health stats etc. Pump on/off, lighting and sensing some stuff.

I'll try my hand at tomatoes and maybe chilli peppers. The initial goal was to grow as much as I can which goes into home cooked chilli :)

Raspberry Pis and CHIPs: good for a home automation hub of sorts or a thing where you want a portable computer capable of working with video, audio, or large volumes of data. Arduino et al: need to have buttons do more complicated things than buttons can actually do: slowly change light colors, actuate things, CNC, etc. ESP8266: sensors and remote controls for switches and such. Anything Arduino does above, except th…

I'd say the Teensy is in the Arduino++ camp there. It uses the same libraries, etc, just has more power processing, a pretty nice price, and some interface bits and pieces that are very nice, like being able to act as a usb device and host. A lot of hardware, I'd argue is better to be treated as a library -- there are libraries and hardware that have definite feature sets, some of which overlap, that allows you to ch…

The ESP8266/Wemos can run Arduino too. Over the summer I built a wifi clock, but couldn't get any of the native LCD libraries for the ESP to work. I flashed Arduino and used the LiquidCrystal library, initially just to make sure I had wired stuff up correctly. But then it worked, and I decided to stick with it :)
