I’ve been trying to track down on my Rumba board, for all the exposed pins & connectors, what their equivalent Arduino pin numbers are. This has been… surprisingly hard to track down. For example, it looks like the “Fan1” mosfet = Arduino pin8. In addition, there’s an expansion port on the left, I’d love to know what all those pins relate to. Any thoughts? Thanks

Lemme guess, your battery died so you dissected it.

lol, no, everything works fine. I just want to know what other pins are available to play with :slight_smile:

Marlin should have a few Rumba pin configurations you could base it off of

Yeah, check pins.h for board type 33…and you’re right 7 and 8 are fan0 and fan1

Interesting: My pins.h has no ‘board33’, but it does link me to pins_RUMBA.h : there’s stuff in there for sure. Guess I was hoping for more of an image :stuck_out_tongue: Talking to a buddy with a rumba, his pins are actually different from mine. Chaos.

Ah, you’re right…it was board 33 in an earlier version of Marlin…and yeah, my rev of Rumba looks different from the wiki in a number of ways.
