Update on my new G-Blade using Rpi as controller with  Starminer software. It's been running over 18 hours now and appears stable except for a power bump yesterday, about 5 minutes outage. I apologize for the photo quality but it's clear enough to see the performance. The latest Starminer release is running  CGMINER 4.3.5

First jpg is temp setup with RPi.
