I am trying to build out a new home automation box and want to incorporate a Google Coral TPU, specifically an onboard one, because the usb devices are not well supported by proxmox in my experience. I was hoping to get a dual TPU module that fits an e-key wifi-card slot but it looks like it requires both pcie lanes to be provided.

To use both Edge TPUs, be sure your socket connects both instance…

Thanks in advance.
