tl;dr: It's the same device as before in terms of processing, but with less RAM and fewer connectivity options (and therefore cheaper)

More than that.

They dropped Display Port, the second CSI Camera Connector, the M2 slot, the USB slot and replaced the barrel jack with the USBC.

Thats a decent downgrade of capability

USBC power is an improvement though!

Edit: But no WiFi is annoying.

Depends on your usecase. If you try to connect it to something like a battery or a generator, USB C is definitely a downgrade.

I guess that's true, but many projects I see use USB power banks for arduinos and I don't think this is too different.

The 4GB Jetson will run off a micro-usb port (for power banks) OR the barrel adapter.

I run the barrel adapter off a power bank just fine

4gb one over micro-usb real needs to be in 5w mode disabling 2/4 cpus. Running off usb-c at 15w where I can use all 4 is a big improvement for convinience for me.

Removing the second CSI Camera Connector is what immediately killed it for my use case :(

I don’t understand why it has less RAM. I would have expected a 4GB and an 8GB version.
