Wikipedia:Articles for deletion/List of Arduino compatibles
this list seems to fall under  to some extent.  A simple https://encrypted.google.com/search?q=arduino+compatible&btnG=Search+Books&tbm=bks&tbo=1 google books search shows that there is much discussion in reliable sources of arduino compatibles as a group.  Furthermore, this list seems to me what the notability guideline calls a "cross-categorization list", about which the guideline states: "There is no present consensus for how to assess the notability of more complex and cross-categorization lists (such as "Lists of X of Y")"  It seems to me that in the absence of consensus for guidelines for establishing notability of such a list, and given the fact that the subject of the list ''as a group'' is notable, it is more than reasonable to rely on the consensus of the multitude of editors who have had in-depth and lengthy discussions about splitting this off from the arduino article (see Talk:Arduino#List_Of_Arduino-compatible_Boards_and_Shields) and who have done an excellent job and put in a lot of high-quality work on this article.  &mdash
