[Freedombox-discuss] Interest in Another Hardware Option?

We are using the BSP from NXP with Yocto to create boot images. I am not
sure if the BSP and drivers have been up-streamed. I'll look into this.

We have calculated peak consumption of the full assembly at 15W, but I'm
not sure if this includes load on the USB and/or PCI-e buses.

The power supply does need some design. In our products, this assembly
plugins into a back-plane that supplies 5V at up to 4A. We would need to
design an interface to an external DC supply.

I think USB Type C could be a good option, though I'm not sure what effect
this would have on cost. Prior USB versions might be an option if we can
keep consumption below 10W.

Thank you for the suggestions and referrals, Peter.
