New Power Shield

[NixHydra]

Hi Felix,

   Noticed you are now selling a revised version of the Power Shield. It would be appreciated if you could outline
the reasoning behind the revision and describe the differences between the two Power Shields?

                                              cheers,

[Felix]

Hi NixHydra - The reasoning and differences are described in this blog post: http://lowpowerlab.com/blog/2014/06/08/powershield-r2-released/
