A while ago, Francesca from Element 14 kindly contacted me to ask if I wanted to receive some products from their catalog for review. I said yes and since I already had a wishlist going on (as most electronics guys have) it was easy to pick up some products. I also considered current and future projects when picking the items and so I had 4 items:

I asked for the STM32VLDISCOVERY because I wanted to play with one of these ever since I discovered this STM32 book written by Geoffrey Brown. The book seems so nicely written and from a practical point of view seems like it will get me started and working on the STM32 in no time. I’m also working on a couple of projects right now for which the STM32 might seem like overkill but I might use it anyway just build some experience around this chip.

I asked for the ATXMEGAA3BU-XPLD because it is a nice platform all around. The MCU is the ATxmega256A3BU and you also get some analog sensors, an lcd display and lots of IO’s. Excellent for when you need to throw something together and test it on an Atmel ATXmega. The ATSAM4L-XPRO which I received in error, features Atmel’s ATSAM4LC4C Cortex-M4 MCU which is nonetheless interesting in the industry but isn’t of much use to me on it’s own without some expansion board.

The TPS54231EVM-372 and TPS5450EVM-254 from Texas Instruments were requested because I use both of these in two of my projects and I wanted to have a reference testing platform for comparison to my own implementation in layout and design. I use the TPS54231 in the new Audio Spectrum Analyzer to power the digital/LED section and I use the TPS5450 in my DIY digital power supply as the switching  pre-regulator before going into a linear reg.

More will follow on these as I am going to perform some measurements like output noise on the TPS54231EVM-372 and TPS5450EVM-254 using my entry level scope and compare the results with the ones from the datasheet.
