@@ -13,3 +13,17 @@ holes in the USB micro connector footprint have been plated (they are
 correctly marked as unplated). This allows the shell to short with Vcc
 so it was necessary to lightly drill the holes to disconnect them from
 copper on both top and bottom.
+
+## Revision 2
+
+Changed to use a FT230X chip and a single gate OR device and designed
+the board to fit into a Hammond 1551G box.
+Sent for manufacture Oct 2017. The 74HC1G32 footprint is incorrect and
+boards required rework to connect this properly. Once done the boards
+work fine.
+
+## Revision 3
+
+Corrected the 74HC1G32 footprint.
+Added a solder jumper (open) to the 5V pin on the main connected
+as typically the device should be independent of the bus voltage.
