Arduino Uno for $2, NodeMCU for $3, RPi for $5... please let this trend continue. A year or two, and we'll basically have computronium - simple dev boards powerful and cheap enough to just tile your house with them. I've recently figured out that there's no point in designing your own PCB for placing sensors at home, when you can get an Arduino and an ESP8266 for $5; add power (and some ~$0 of voltage regulation) and…

While I agree completely with what you're saying, I think it's almost unfair to be comparing this to an Arduino or NodeMCU - this is orders of magnitude more powerful.

As a programmer who used to like taking things apart and playing with solder in school seeing these kinds of things fill me with enthusiasm and joy - and then I remember I need a wired power supply or a battery and suddenly enthusiasm is gone :( I wish we had wireless power transfer - for these kinds of things losses wouldn't even matter.

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.

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.

Broadcom must be delighted to have managed to find a use for their obsolete part from 2007 or so. Some accountant, somewhere, is happy :-) Probably a neat little board too, but unlikely to be $5. It's at £11.88 [0] ex VAT ex shipping at farnell UK (and can't be ordered anyway) -- that's more like nearly $20 these days. [0]: http://uk.farnell.com/raspberry-pi/raspberrypi-zero/sbc-zero...

On the cynical game I'd add that selling a pi zero at 5 then many phats to get audio, network etc, might provide more global revenues and maybe more profit :)

I suspect this is in competition to the currently-being-released Micro Bit, the BBC's similar tiny computer (The microbit isn't aimed at the same market, as it has buttons and LEDs built onto it, and no HDMI. But it is threatening to push the Raspberry Pi out of UK schools).

To what degree are the power requirements on their faq still valid for the pi zero ? https://www.raspberrypi.org/help/faqs/#power The question I really want to ask is, how long will a 1.2A supply last with nothing else attached to it ?

Reportedly draws ~80 mA idle and ~160 mA [1] (I assume with no peripherals whatsoever). So a 1.2Ah battery should last between ~7-14 hours.
