ganjadude (952775) writes "I stumbled upon this little scoop and thought the Slashdot crowd would be interested in. The new kid on the block, known as the HummingBoard can handle faster processors, more RAM and will fit the same cases for the Pi. Also, you can expand the memory and the CPU is replaceable! The low end model starts at $45 and the high end costs $100. So tell me guys, what are you going to do with yours?"
$45 model is a single core iMX6 (an ARMv7) with 512M of RAM, the $100 model has a dual core i.MX6 with 1G of RAM. Full specs.

I built a baytrail server and its amazing for the cost and power budget. The Intel HD graphics aren't for gaming but it can serve and render media on a sip of power. The HDDs are by far the biggest power hog. I struggled with these ARM chips and their custom distros enough. The ability to be on x86 with well supported peripherals is well worth it - gpu especially. Need to run some wintel stuff now and again? Virtualbox works fine. On the other hand ARM chips always have their issues with proprietary gpus and their binary blob drivers rife with kernel compatibility problems. And you find yourself stuck in a back alley of "mostly" compatible software and patches.
You might hate sucking up to Intel but at least the drivers work. I might be burning 7 watts instead of 5 but that's nothing in the overall power budget. And baytrail is much much faster than IMX6.

PSU maximum output current is a pretty bad way to determine that.
TDP is the thermal limits. Chips can use more for short periods and will use much less when idle.
btw, those PSU's also need to power the hard drive, memory, chipset, wireless card, etc...

The use case for swapping the CPU/RAM module yourself looks pretty weak; but it would appear to make sense for the manufacturer: This 'hummingboard' appears to be their existing 'MicroSOM' [solid-run.com] product attached to a fairly rPi-like breakout board.
If they already make and sell those, they'd likely have to churn out a lot of hummingboards before the savings on connectors makes it worthwhile to integrate the CPU directly with the board.

Connectors are amongst the least reliable parts of any electrical system.
Paradoxically it's the least used ones which give the most trouble as most designs don't provide enough contact pressure to overcome oxide growth (and there's also tin pest to contend with), and most designers don't know enough to use the right designs.

It's a similar problem. Except since this is a much larger connector(100 times as many pins?) with smaller pins(1/4 the size?) and uses a specification that is used by far fewer people than USB it's MANY MANY times more likely to have an issue than a single USB port.
In reality computers solder USB all the time for lower-bandwidth devices(e.g. Bluetooth, WebCam, SD reader, InfraRed, ethernet, WiFi, etc). It's dramatically cheaper and slightly more reliable than including a full USB port because you don't

Sure - I'm using a Dagu Magician 2WD Robot Chassis [dawnrobotics.co.uk] as the base. The motors are connected to a L298N [youtube.com] which is in turn is connected to the Pi and a 5v mobile phone battery pack. This allows the low powered (3.3v) Pi to power the more demanding (5v) motors.
The Pis power comes from a second mobile phone battery pack, it gets it connectivity from a USB Wifi dongle and finally vision from a Microsoft LifeCam VX-5000. The bendy bit keeps the camera snuggly in the chassis without need to screws.
Software - I'm using mjpg-streamer [sourceforge.net] to stream content over HTTP and a small home made Python application to provide a REST-like web API to control the motors. This is not perfect as the streaming is not designed for real time, so if it falls behind it does not easily catch up without hitting refresh.
It was a fun project, cost ~£100 in total and took less than a day to build and put the basic software together for.
The second project I want to do is attach a Robotic Arm [maplin.co.uk] and a bunch of cameras to a Pi as well as a small in car TV screen. Then using a better video conferencing solution than mjpg-streamer have a static robot at my daughters house which will allow me to be able to play basic board games over The Internet.
Hope that helps, good luck with your project.

Hi there,
First of all. Thanks for posting a link to our website (Dawn Robotics). We're a small company so notice a traffic spike even with just a Slashdot comment. :) Secondly, for people who are interested in building Raspberry Pi robots, we sell a Raspberry Pi camera robot kit [dawnrobotics.co.uk] that doesn't require any soldering and which you can drive around using a web interface on a tablet, smartphone or PC. We also have blog site [dawnrobotics.co.uk] with lots of robotic and Raspberry Pi tutorials.

The power consumption of the RPi (especially if you're not using the GPU) is tiny in comparison to anything with motors in it. I'd rather trade a slight reduction in battery life for being able to use a rich programming environment than save a few mW and be forced into a constrained microcontroller development environment. It might be different if I were planning on mass producing a few thousand and needed to save costs, but for a hobby project or even a prototype I'd happily overprovision on CPU power.

There are plenty of development boards that come as a base board with several CPU/RAM options on a daughter card. Just the fact that it fits in a raspberry pi case may make it a bit more interesting for some people. However, if you're truly into developing, you're either going to stick with the pi or get the board with the hardware specs you need and not worry about the form factor. If you're into the Pi as a consumer, it's most likely because of it's media playing capabilities. Unless this board will support XBMC with proper hardware acceleration, it's not going to be relevant for those folks either.
