I am working on making a version of this board for the BeagleBone (Cape-RAMPS, or CRAMPS), and am somewhat limited on pins (the BeagleBone Black looses a lot of I/O if you want to use the on-board flash and HDMI out).
I am trying to understand the expansion connectors: Aux2, Aux3, and Aux4
I see Aux3 is used for the extruder expansion board design, but notes on the schematic seem to indicate this is a standard connector. Are there other boards that connect to this header, or any sort of a standard for the header pinout and signaling?
And what are Aux2 and Aux4 intended to be used for? Are they simply connectors added to RAMPS-FD to make use of available extra signals, or are they somewhat standardized as well? Are there any designs in-progress using these connectors?
Finally, I'll likely have to move things around a bit to account for the dual-row BeagleBone headers. I assume I'd need to leave the relative placement of the Aux headers consistent if an expansion board for the RAMPS-FD is to be used on the CRAMPS design. Other than the Aux connectors, is there anything else that really need to have the same relative spacing (I2C headers, serial headers)?
