[QUOTE="rfq, post: 638776, member: 15523"] [b]UPDATE: 20 DEC 15[/b] I am busy getting the controller up and running. In doing so I discovered the smaller PSU for the digital side, cannot supply enough current. The moment I put an LED on the board to debug the micro, the whole thing collapsed to 3V odd and the relays let go. So I have put a 3VA transformer in place of the 1.5VA one, and that solves the problem. Enough current for everything. Small oversight on my part, but this is why I breadboard things, so that when it goes to PCB layout, there's no mistakes. [/QUOTE]
