A nice surprise in my news feed this morning. The new Raspberry Pi 2’s are now on sale. The little Pi just got even better
Very cool! I can’t wait to get my hands on a few of these.
I’ve been using a BananaPi and loved the upgrade over the original RaspberryPi. http://www.bananapi.org/p/product.html
I also like the Banana Pi, but if you think that’s fun, you ought to check out the ODROID U3. I got one as a present, and it’s amazing.
Oh… a new toy for me.
I love my U3, I use it for all sorts of stuff. I’m thinking about picking up an XU3 Lite for the 4 extra cores.
They also get Windows 10 for free
That’s a neat feature, but I have to say I’m less excited about it, myself. Windows is becoming a decent OS, don’t get me wrong, but unless they’ve added it, there’s not a good remote console. It seems like a waste to pile all that GUI overhead on a perfectly good raspberry pi.
Does anyone know the power consumption of the Pi 2 vs the B+?
Just happened to be reading this article on hackaday
I just so happen to have a FriedCircuits USB current/voltage/power meter sitting around. When monitoring the power consumption of the Raspi 2, there is a slight increase in power consumption over the Raspberry Pi 1.
When booting to a Raspbian desktop, the Raspberry Pi 1 draws about 290mA, dropping to about 250mA once the desktop is loaded. The Raspberry Pi 2 draws about 340mA at boot, dropping to about 270mA once the desktop is loaded. There is a slight increase in current draw from the Raspi 1 to the Raspi 2.
With a few experiments, I did determine the Raspberry Pi 2 will draw up to 500mA under heavy load. That’s the max spec for USB. If your current USB power adapter isn’t great, you might want to get a better one for the Raspi 2.
Thank you! Great find!
Good information. I use several SBCs to host coin wallets. Even at full load, the rPi2 only draws 55W. At my power rate ($0.11/KWh), that’s $0.0066/hr, or $0.16/day. That’s a small fraction of the power draw my primary machine uses.
Watts = Amps x Volts
Watts = ( Amps = milliamp / 1000) x Volts
Watts = ( Amps = 500mA / 1000) x 5v
Watts = 0.5A x 5v
Watts = 2.5W
1000W = 1kW
2.5W = 0.0025kW
0.0025kW x $0.11 = $0.000275/hr
$0.000275/hr x 24 hrs = $0.0066/day
$0.0066/day x 365 days/year = $2.409/year
I want some of these. They are way marked up already.
The quad core CPU means we will have a good unit for all sorts of mining .
I bet Minera will be awesome on it.
I need a US seller of these that takes Bitcoin.
If you’re looking for raw processing power, check out the ODROID U3 or XU3 Lite. They’re a bit more expensive, but have quite a bit more horsepower. And they’re actually in stock.
They had the same stock issues with the first rPi. It may be a couple of months before these are commonly available, and possibly longer before they’re available for purchase with Bitcoin.
Good Point I remember trying to get them when they first came out it was slooooowwwwwwww.
I will look into the Odroid.
What OS do you use on it and what do you control with it?
Yeah, it took months to get one when they released.
I’ve got Ubuntu Server 14.04.1 on it right now. The ODROIDs run a full release OS, so you can put whatever you want on there, as long as it’s got ARM support. I haven’t got any active hardware miners at the moment, so it’s hosting a few wallets, some project services, and is currently my small project development box. I haven’t tried it with an X server yet, so I can’t speak to that, but it’s more than able to handle everything I’ve thrown at it so far.
I might have to get one and get an OS on it.
Lots of fun.
Seems I’m missing out on all the fun topics. I have found that having a 1.2A power brick is essential to have stable operations I usually buy the 2A version to be sure. If you add some USB stuff it’s really needed even though USB keyboard mouse or wifi adaptor don’t pull much current a minimum of 1.2A is recommended. The specs say a 750mA is enough but I found that is not the case the RPI becomes quite unstable with those power bricks.
