Moving from OSEPP UNO R3 plus to Blend Micro by RedbearLabs


I've been using the UNO R3 Plus and would like to add BT capability. I like the form factor of the blend micro by Redbearlabs. I'd like to move to blend micro if possible.

Are there any key differences I need to know about? Will the sketch load on the blend micro without changes? Any other limitations of micro blend?

thanks for your help,
