I don't see anything about Ethernet/Wi-Fi. Am I missing something?

I understand they had to cut some features to reduce the prize. But networking is such a fundamental requirement for these types of systems, you'd think that it would be the last feature to be excluded.



Can the HDMI port be abused for some kind of networking?

There are a whole bunch of extra features tucked away inside HDMI. I know the Pi doesn't support Ethernet-over-HDMI, because it's missing the necessary PHY, but apparently it does support I2C-over-HDMI. I2C isn't very fast (tops out at 3.4Mbit, if you're lucky); is there anything else which could be used hidden inside somewhere?

One interesting thing about I2C, though, is that it would be cheap and easy to build a chassis with a whole bunch of these $5 modules wired together via I2C. It's almost certainly not cost effective in any way, but would be interesting, particularly if you could get useful work out of it...


The networking on the other Pis is attached via USB. It's a very easy and obvious thing to drop.


Yeah I guess.

Still, I for one would be more than willing to pay a few extra bucks for a stripped-down version of the Pi with wireless included.

Actually, all I'm looking for in this type of machine is Linux, Wi-Fi and GPIO, in a reasonably compact format. Maybe the Pi isn't a good fit, since it is more about "teaching computing" than "building your IoT stuff".


Exactly. If you need Ethernet, a USB-to-Ethernet adapter is $1.50 on AliExpress including free shipping from China.


And one kind person suggested PPP over serial in comments to the Make article: http://elinux.org/RPi_Serial_Connection#Network_connection_w...


I set up ppp between a pair of RPis a few years ago - you can crank up the speed quite a bit past 115200 baud.


I agree, if this would include an ethernet port it would be the cheapest embedded linux board with wired networking. I would really like such a device and am kinda sad it doesn't exist. Like a ESP8266 but wired.



There's a USB port.


Plug a wipi into it via the USB OTG cable. Done.


No. Wireless adapter needs better power source, so it's RPi to powered hub to WiFi, which makes the setup quite a bit bulkier and pricier.

Like gp I wish some sort of network connectivity can be included to make it more complete as a standalone computer.


Nope, we have hundreds of Pi2's with two wipis in them, yeah it's fine.


You don't need a hub, you need a smartphone charger (one that gives you more than 500mA at output).
