I don’t want to deviate from the main topic, but I have read on another thread that someone used a riser card between the uConsole and CM5. The height increased helped with thermal management because now the CPU touches the back plate.
But perhaps a new riser can be designed to extract the pci-e signals for a nvme disk and also the Ethernet connection using a flex tape and then have a daughter card somewhere inside to populate a small nvme drive and have the native Ethernet port two. That way we can use the usb 2.0 from the RTL-SDR extension board for more appropriate things that does not restrict speed.
PS: this is the riser thread
