Since I discovered the Arduino
micro-controller last October (2010) I have been fascinated by their versatility and ease of use, however I personally find that they tend to be on the bulky size and expensive for some of my permanent projects. I then discovered the Ardweeny
and I just love their size and price; after purchasing a few, I made some personal improvements, especially after blowing the ATmega328 on one of them and finding it a pain in the derrière to replace it.
The concept is simple: reverse the PC board and solder the components on the opposite side, this way a socket for the ATmega328can be added along with some strip headers
These modified versions are meant to be used in small permanent projects, they are not suited to be used in bread boards like the stock units (although with two strips of long male headers they could be used that way) keep in mind that the serial interface is obstructed making them inconvenient to program while installed in the bread board.
If you wish to use them in bread board, follow the kit instructions to the letter, my only suggestion and recommendation is to add female headers instead of the provided strips, see step 4 - Installing the Female Socket Strips,
this way you get an extra set of connections to use when plugged into a smaller bread board.
