+v1
+==
+
+this is a complete re- board layout.
+it does not fit an off-the selves enclosure anymore.
+all SMD parts are on one side to allow easier SMT assembly.
+
+fixes:
+
+- 6-40V power input activated when UFP is connected
+- use current limit on DFP (prevents USB to reset when DFP is shorted)
+- 6-40V power input capacitor now lays down
+- remove copper plane under crystal to prevent impedance error
+
+errors:
+
+- crystal still does not start
+- none of the two possible OCS inputs (Dx04 XOR Dx05) work
+- power dip causes reset when enabling all 7 DFP power outputs at once
+
