This is a new version of the already-supported Arduino Nano 33 BLE Sense. I opened this issue to discuss the now discontinued Rev 1, but I repurposed it for the Rev 2 after figuring out that all the pins for the Rev 1 were already defined for the Nano 33 BLE port. See #7991 (comment) further below for more information.
