Check the listing for details. QSC Q-SYS I/O-8 Flex PoE+ Network Channel Expander (Not a CORE device). Condition: Used, Made in United States. Listed at 500.00 USD. This provides 8 flex and 8 GPIO ports for the QSC Q-SYS ecosystem. This device is an EXPANDER, and requires a CORE to operate. 10.x is not compatible. I can confirm from my experience that the Core Nano does work with this, but you must degrade firm to 9.x.
