The Freescale Kinetis Freedom KL25Z Board (FREEDOM-KL25Z, http://www.element14.com/community/docs/DOC-46626/l/element14-exclusive-kinetis-l-based-freescale-freedom-development-board) is available for pre-order, and expected to be delivered by end of Sept. 2012. I have placed an order for 2 board for my personal use. As I'm teaching Advanced Embedded Systems programming at the University of Lucerne for Applied Sciences and Arts, and as I think that board will be a great lab tool or even a student give-away, I have ordered a bunch more.
I was lucky and received directly from Freescale the Freedom KL25Z board. I think it is from a test production run (same board as shown in the element14 colleaterals).
Anyway, I have described my first steps and experience here:
Enjoy :-)
