+Here is information about the CubeSatSim v1.1 hardware
+
+NOTE: The change between v1.0 and v1.1 is changing the BPF to a LPF.  Only the SMD components change - all the rest are identical
+
+There are files for the main board, battery board, and STEM payload board of these types:
+
+* cubesatsim-main-1.1_gerbers.zip  --    All gerber files used to fabricate PCBs
+
+* cubesatsim-main-1.1_schematic.pdf --   Schematic
+
+* cubesatsim-main-1.1_board.png     --   View of board
+
+* cubesatsim-main-1.1_board_fill.png --  View of board with fill
+
