Stellaris® LM4F120 LaunchPad for $5

[andyg]

Thought some of you might be inerested. TI is offering this board for $5, max 2 per person.  It uses one of their new LM4F120H5QR ARM Cortex-M4 microcontroller. (80MHz, 256kB flash, 32kB RAM, USB). Here is the link here.

And i thought MSP430 launchpad was a high value for money. Ordered two of those new boards. Piety that they start shipping on 25th .

Thanks for the confused spam 

Actually 29th

I've checked one more time and it still says 25th (but delivery time has elongated to 2-6 weeks). I guess it probably depends on your location (?)

Well, I ordered one; it'll be interesting to play with.

I just got mine...  I can't install drivers for my Win8 (64bit) box....

I ordered 2 from Farnell, I expect them Monday (I didn't noticed a max. quantity of 2)
My first ARM µP to 'play' with, that I think will be used in my (to be designed) PCB.

There is no DAC, but I don't think I will need it (via I2C->BT->Phone Apps can make a sound)

Thanks!  That's looking like a better-than-average set of videos...

If you can spare the slightly higher cost ($17.00), you can even try the F28027 Launchpad, which sports PWM outputs (and a slightly higher speed of 60MHz).

bad luck! i ordered 2. but anyway just for fun its cheap, the site says 2-8 weeks delay, bugger, i'll wait.

Huh? Isn't their M4 80MHz? It has PWM pins if i read correctly.

Well, the LM4F description says its Flash memory runs as single-cycle up to 40MHz sustained or slightly higher due to the presence of a prefetch buffer. You will get 80MHz if running your entire code from RAM or if your code calls some Stellarisware libraries (for the peripherals) stored in its internal ROM (single cycle as well).

The F28027 flash memory runs at full clock speed (60MHz) but does not have any library stored in ROM.

Yep, you are right regarding the PWM outputs...

Another interesting thing on this F28x Launchpad is the presence of an isolated JTAG - probably that is what the price difference comes from.
