@@ -0,0 +1,27 @@
+RevD schematic shows (incorrect) AP62301 buck configuration.
+All shipped RevD boards use AP63205 buck configuration; the AP62301 buck never shipped.
+The changes below are for the (correct) AP63205 configuration.
+
+All RevD PCBs I've shipped are assembled correctly.
+This issue only applies to the schematic.
