+This folder demonstrates the differences between the v1.0 and v1.1 designs.
+The main difference is the replacement of the crystal used from a 32.5 KHz
+crystal to a larger 100 KHz crystal. 
+
+As shown in the two schematic pngs, each crystal is wired up in the same 
+fashion to the microcontroller chip, with the newer crystal requiring 
+slightly larger capacitor values.
