Power Supply Design Flaw

It is a long established truism that power should be transmitted at high voltages and stepped down at the application -- 5V in was simply a bad mistake born of tunnel vision from the SBC Pine64.

I must agree.  My SBC(s) are 12v systems (stepped down and filtered) including my supply for the pinebook.  You can easily get the correct supply from the Pine Store.  Also, you can get a 1m or 2m usb cable with the correct (quality) plug ;  I use the cable with my 12v-->5v CPT and passive filter design.
