Seems Raspberry Pi have release the RPi Zero - a mini Pi released for $5!
(Sadly, this has the geek in me really excited… ).
Specs as follows:
A Broadcom BCM2835 application processor
1GHz ARM11 core (40% faster than Raspberry Pi 1)
512MB of LPDDR2 SDRAM
A micro-SD card slot
A mini-HDMI socket for 1080p60 video output
Micro-USB sockets for data and power
An unpopulated 40-pin GPIO header
Identical pinout to Model A+/B+/2B
An unpopulated composite video header
Our smallest ever form factor, at 65mm x 30mm x 5mm
Of course, dont know what availability will be like initially (probably akin to hens teeth), but - could PiAware be made to run on this?
(One for FA Admin devs probably - will PiAware compile for that chip?).
Could really open up PiAware - both in terms of cost-of-build and build size, for example, you could probably mount this on your masthead even easier than the “PI2 in an icecream box” that seems popular!
I have an original Pi B running my adsb stuff. It uses a hub to provide power to the pi and wifi and radio dongles. I had everything connected directly to the Pi previously, but when I changed to the 820T2 dongle from an E4000 it wasn’t stable as the 820 draws twice as much current.
It would be easy to swap the Pi B out for one of these - if there is a decent performance bump I may do that, but I already have the Pi B overclocked to 1Ghz.
Firstly, yup - MagPi did have the Zero free today (issue 40) - I reserved and picked up 3 of the 6 my local tesco’s had - a second for me, one for my dad and one for a colleague.
In hand, these things are certainly small!
@Obj, yes - with only the 1 micro USB for data (the others power-in), I’ll have to use a Hub. although maybe not a powered one as the Zero uses something crazy like 167mA…
(I’ll try it and see - I imagine Wifi + RTL dongle will use a fair bit).
Of course, I’ll need a min of 2 usb devices off the hub.
Either way, I’ve got some other projects that would benefit from these - and if I can get it to run piAware, I’ll report back!
The Zero is also oc’d to 1ghz - 512mb ram etc, so not much in the way of an “upgrade” over the B+.
What I think the Zero gives is size optimisation (it’s not a lot bigger the RTL dongle itself) and also power usage - something like 170Ma afair.
Also, the fact that it’s like £4 I believe opens up ADSB like this to even more people or even more receivers - I for one can think of a few other places I could put additional receivers.
Of course, the low power usage may open up more options on remote (i.e battery / solar powered) installs.
Although, yes, one does have to consider a powered USB hub…
Micro HDMI: Does anyone have any extras of these laying around? Gonna have to go out and buy one…
1 Micro USB Input: Now an external USB hub is needed as well as a micro USB cable to replace the normal USB cable most all hubs come with…
Power savings?: Yes uses less power but the external hub will suck up just as much if not more…
By the time you add the needed extras that small fingerprint becomes a larger foot print than a RPi2 for what we do here for about the same price as just getting a full blown RPi2 with 4 times the CPU and double the memory.
Never handled one so this is an opinion based off pictures and specs and comments.
Doesn’t look bad not all stripped down. Actually would be interested in giving one a try in the future.
Comments on the page selling it point to it being in the early stages of development however.
This begs the question will all the hardware work properly with your chosen operating system…
Everything I read on it it’s the equivalent of an overclocked Raspberry Pi Model B+ as far as performance goes which is defiantly not bad given the size. Never ran PiAware on a B+ but sure others have and could report back.
The developers were targeting a group that have trouble affording a $35 Pi. It may not be simple to run Piaware on it. With the reduced power needs, I don’t think it will be long before someone hangs it on a balloon with a camera and sends it up the the edge of space.
My PiAware station is running on a B+. It runs just fine without any problems. As of today, my logging streak is 456 days. So the pi zero should run just fine… you just need to get a USB hub, USB micro to USB host adapter, WiFi dongle, and an SD card.
Personally, I am more interested in the $9 CHIP. (and I hope to finally get mine by January). Its a little more powerful, offers integrated flash, WiFi, BLE, and twice the GPIO. CHIP will likely be the lowest cost device since you don’t need to buy any SD cards, WiFi dongles, adapter cables, etc. It does lack HDMI (though you can get a HDMI board) but I wont miss that since it is only ever connected to the monitor/TV just long enough to enable SSH (and that can be done using the composite output).
