I started to daisy chain 2 Axolotis and a little mixer with the + - pins next to the dc input.
So dc is coming from a wall wart or battery into the dc plug of board 1 and is being split via the two + + pins to board 2 (also to the pins) and a mixer. - is connected via the - pin of the other bord and gnd of board 1 to ground of the mixer.
Is this a good Idea? anything I should be careful with?
