Although the new Raspberry Pi B+ did not have as many improvements or enhancements as originally hoped, more memory and more built-in USB ports are always good. The B+ unit uses a MicroSD card vs the regular SD card of it's predecessor, and the RCA video output has been removed. The power supply connection has also been replaced by Micro USB vs Mini. The immediate issue was the incompatibility of the cases made for the preceding model and this one. Furthermore, there were no B+ cases available where I purchased my units - so my new RasPi B+ cluster was treated to a stackable custom LEGO casing as shown.
