Just a heads up...

I mean cheap as in $4.99 - great value! I've just noticed it at TI's site and ordered two (the maximum). I bought some of their previous $4.99 kits and they are well worth the few $. You need a TI 'account', but it's just a case of signing up.

See here: https://estore.ti.com/Stellaris-LaunchPad.aspx

The Stellaris LM4F120 LaunchPad Evaluation Kit includes the following items:

    Stellaris LaunchPad Evaluation board (EK-LM4F120XL)
    USB Micro-B plug to USB-A plug cable
    ReadMe First quick-start guide

The Stellaris LM4F120 LaunchPad evaluation board offers these features:

    Stellaris LM4F120H5QR microcontroller
    USB Micro-B connector for device
    RGB user LED
    Two user switches (application/wake)
    Onboard Stellaris® In-Circuit Debug Interface (ICDI)
    Available I/O brought out to headers on a 0.1" grid
    Switch-selectable power sources:
        ICDI
        USB device
    Reset switch
    Preloaded RGB quickstart application
    Supported by StellarisWare® software, including the USB library and the peripheral driver library
    Stellaris® LM4F120 LaunchPad BoosterPack XL interface, with stackable headers to expand the capabilities of the Stellaris® LaunchPad development platform

The EK-LM4F120XL works with StellarisWare, as well as several different software tool chains, including:
    Keil
    Sourcery CodeBench
    IAR Tools
    CodeComposer Studio

Seems like a no brainier, if you are looking for (or have interest in) a small ARM developer board...  For $5 a pop, I will certainly snag a couple...

Yeah, I forgot to say it even includes shipping (at least to the UK). A real bargain!

I wish I could get more,
They are great for those little projects, you can later modify to suit.

It might be limited just during the initial release period, to make sure that TI has enough for everyone. Other boards that I have bought from them at around that price are still available at the same price and don't show an order limit any more.

I'll be keeping an eye open for more myself.

That is an amazing price. Two off including delivery charges to the UK for less than £6.50!

I've never looked at Stellaris, but at that price ... why not  Smiley

I just ordered two of the boards, and there is no price adder for shipment to Germany as well!

I as well followed suit and ordered 2 . Now I just need to figure out what to do with them... Seriously!
The deal was just too good to pass up. I am certain they will get used for something cool.

The MSP430 boards seem like a good deal as well.

I wish the motor controller eval boards were priced like these, though. $300 is too rich for me.

To be fair, it's clearly listed as a "preview" chip and the samples of the subset chips is listed as an "experimental silicon" and thus should never be implemented or used in anything but testing and evaluation purposes...  A new revision came out in August with lots of fixes, and I'm guessing the boards will have the new version on them...

I have a couple of those MSP430 LaunchPad boards. They are a good, and amazingly cheap, way to learn the MSP430 and TI's code Composer Studio.

It's the DSP boards I wish they would do a cheap version of.

I recently received an email advising me the two boards I ordered 3 Sept now had an estimated ship date of 16 Nov.
I’m hoping this does actually suggest they’ll be the newer mask. Also, looks like Rev D data sheet was released 6 Sep.

TI Store page now says “Orders placed after 25-Sept will be shipped within 8 to 10 weeks.” Has anyone received theirs yet?

I've had a similar email. I don't mind waiting longer for the 'improved' version and I imagine that is what TI will send, otherwise they'll just get people complaining.

The user manual for the board wasn't available when I first found it, but is now: http://www.ti.com/lit/ug/spmu289/spmu289.pdf

TI have made the expansion headers compatible with add-on boards for the MSP430 kit. Not that I have any, but it's a good idea on TI's part.

What is great is the 10 youtube videos and the accompanying tutorial book - the Stellaris EK-LM4F120XL LaunchPad Workshop . Although it does uses the Code Composer studio for the workshop examples, you can still go with Keil, IAR or other.

The Youtube videos and book has made its way to my tablet PC and I will surely find a lot of odd moments to educate myself.

You can just order them from Farnell, they have 503 in stock (Farnell Export, for EU). Also Mouser has 57 in stock.  Cheesy

Lol - you're right! £3.76. It even says the are UK stock, so no 'one off import fee'.

http://uk.farnell.com/texas-instruments/ek-lm4f120xl/eval-stellaris-launchpad/dp/2192061?Ntt=LM4F120

Maybe that's why we haven't got ours yet - they've sold them all to the distributors!

Has anyone tried to use this board as an external stellaris programmer?

I mean connect the programming pins (they are broken out with 2.54 spacing on the board) to a Stellaris on another board and program it. I we will have to either power down the processor only, or cut the traces to the on-board Stellaris. But at that price, no worries!!

If this can be done, we will have a 5$ programmer for any Stellaris board! Smiley

I will try it once I have the time... Sad

I noticed it dropping - popular little things! It's a bit poor of TI to keep us waiting, but such is life, lol.

It would be great if they can be used as a programmer for other chips. I don't see why not given that the board is claimed to work with the standard software tools, unless the onboard ICDI firmware is crippled. I bet it works.

I have first hand experience of bringing a stellaris (post TI takeover) product to market and it wasn't a pleasant experience!

It took us nearly 9 months to get a production quantity of silicon, partly based on the fact that we had to keep signing waivers and such like because of all the bugs in the silicon and partly because when they released a new version of silicon it automatically cancelled the order for the previous revision of silicon.

When we eventually got some silicon, the revision we ended up with had issues with its core voltage supply that required you to bypass it and supply an external 1.8V rail - so we had to build this fix into the design.

Further revisions of silicon fixed this problem, but I think the one after that had a horrific errata on USB (iirc).   Our distributor was offering us silicon and we were having to to cherry pick which versions of silicon we could use because they all had a variety of really nasty errata, you just had to pick the best of the bunch of what was available.

The stellaris software (stellarisware) was pretty good, I fixed a couple of USB issues which were fed back into the stack, but it still makes me shudder all the problems we had with silicon.

I've never had seen an ARM microcontroller with so many issues!

Needless to say, it was the only stellaris project we did.
