I thought of this as a way of making the interconnecting wiring a little simpler and neater, that's all!

I'll get this drawn up & design files with Gerber's posted in a day or two!

I think I may be reading this incorrectly, but please bear in mind that the supplies to the meters must be independent, as stated on P14 of the manual.

I might well get around to some construction of mine, but there is so much on the "round-to-it" pile that I can't make any predictions. Perhaps lockdown for a few more years? (only joking!).

Colin.
