Comparing the revisions 1.4 and 1.5 I can at least notice one difference. The 1.4er board switched on/off background light in visibly one step to prefered orange scheme. The 1.5er board performs a intermediate step of about 1 second blue scheme for switching on/off the orange coloured background light.
