Looks great. What is it?

I agree I want one. What is it?

A low-quality attempt to cash in on Raspberry Pi.

Can I mod it to play pac man or donkey kong?

I don't know, can you?

can it get teletext?

Wonder if this could be used for arduino-esque projects?....

Good price for a dev board. I think it will be lost on 99.99% of the people here though.

I bought two when it was posted on Hackaday - immediately afterwards HSBC stopped my credit card due to unusual activity...
Trying to get my bank to believe I was me was so much fun. Hope the boards are worth it!

Yes

No ... its completely different, you can't compare to that, its a micro-controller, not a micro possessor, designed for a different market i.e. low end and cheap e.g your washing machine (slightly unfair, better than that)... seems a good price for what it is

It has 256KB of flash and 64KB of ram ti.com/pro…5qr

So long as you bear in mind there are one or two differences
Such as it's got a completely different development environment, no shields, different architecture, interfaces, breakout and capabilities and an incomparably smaller user / support base.

Looking at the development tools, this board is intended for professional embedded developers.

HedgyHoggy

I don't know, can you?



I can if it's technically capable. But I'll have to dress up in my Dungarees and insist people call me Mario first.

They take paypal as well, I ordered two to keep my msp430s company.

You sure its not 99.99999% X)

Anyone know if this would be suitable to use as a light sequencer controller for LEDs? (modelling).Seems a very good price for a cheap microcontroller board.

Used to enjoy coding in assembly, C, etc years ago. Would this be good for me? Can you easily get at the nity grity or are there many layers of abstraction and APIs that you have to learn. Would it be easy to get working I/O stuff?

For those who are curious what it does read here. here So if you never heard of anything similar then you are most likely not able to make use of it.

i would guess its ideal.
great price. wonder how much the P&P is ?

Going to buy one and build a remote control plane for my cat.


You're either trolling, don't know what you're talking about or just stupid!
These types of boards have been around along time before the raspberry pi and are different kettles of fish all together.


I think there's a free C compiler/environment for this.
The arduino (and its copies) or just plain ATMEGA are easy to get into.
Or the non-arm TI board (The msp430 launchpad) is pretty cheap and I'm fairly sure its got a free C environment. You can order both at the same time!

Yeah It would be suitable for this - Depends how small of a board you're after!
I think UK P&P is free

I don't think Texas Instruments should be considered low quality, either.

I like my .net microframework board :P

Fortunately, it won't be lost on the basement-dwelling geeks!

I could have one stuck up my ass and I STILL wouldn't know what it was.

Sounds cheap though so maybe should get some?

Just ordered one, been meaning to have a play with a microcontroller since I never got round to it at uni. Cheers OP!

these would make good washing machine micro-controllers Think of your micro controller as more off a programmable switching device. a modern day one of these http://www.p-wholesale.com/upimg/2/195a1/automatic-washing-machine-timer-245.jpg
only it can do a lot more than one of these.

I think it's probably better to get an Arduino Uno for £17 instead as controlling lots of LEDs even in an array is complicated but with Arduino you can get a lot of support and pre-made code.

Nerds lol

Thanks, ordered a couple.

I'd not heard of this before today.
I don't fully understand what it is,
I have never ever even considered purchasing one of these before.
I wouldn't know what to do with it if I had one.

But it's £3.20

And as it has been posted on HUKD, for some reason I want it now.......this site is like Crack.....will resist ! (I hope)

Would 1000 (in parallel), finally run Crysis at a permanent 60fps?

You clearly know about Dev boards...

The Terrorists will be using these to make more sophisticated IED's rather than sticking to dodgy Washing machine timers...

Only a thought !

No, I hope you're joking.
I have a few Arduino boards, will stick with those (easier to program and plenty of code available, so foten can just resort to copy/paste jobs, saves time and I still learn... double win!)

The smarter option would be to buy 2 pentium 4 ht 2.8ghz processors, stick them together with super glue, get a cheap mobo, psu, ram and case. Wallah! You now have a dual core 5.6 ghz pc that can run Crysis @ 200+ fps with 4k resolution.
