Allows the PC to interface with the dance pads and lighting hardware, the ATXMEGA IO is the new USB IO board for MK10/LX cab-compatible Pump it Up versions (PRIME 2 and above). Notably, this IO polls the pad sensors significantly faster than the previous IO board, the PIUIO. Also unlike the PIUIO, this mounts outside of the MK10 in the surrounding cabinet instead of slotting into a PCI slot.

A few minor variations of this board exist:
LXIO: Designed for use in an LX cabinet.
MK10IO: Designed for use in older Pump it Up cabinets, includes adapter cabling to convert from the wiring used by the JAMMA PCB to this new board.
