first look at rev B0!

comparison of usb3sun rev A3 vs rev B0, top sides of pcb, with silkscreen and smt components visible. four packages in sot23 are now two in sot363 (plus one), and those and several other components are now under the display module. comparison of usb3sun rev A3 vs rev B0, top sides of pcb, with silkscreen and smt components hidden. there are new components for “break preventer” and “display reset”, the sun interface has been miniaturised, and those and the led current sources have been placed and routed more efficiently.

added a couple of mosfets for resetting the display and preventing serial break on reset, but i ended up having to rework the whole sun interface to get everything routed.
