Can anyone help with a wiring diagram for a 7chambers MoM using the helper board?
I think you better ask the people who make that helper board.
With sufficient documentation on how the helper board works, we can help.
This is a picture of a helper board without the leds and switches attached, but it shows all of the connections. I was told by the makers that in its current configuration I would have to program the accents using subblade, but if I cut the jumper pad between the leds I can run them as independent blades. Which should work with the config I have set up with 3 blades, my main blade, the green accent and the red accent.
subblades are better
less wires that way.
