+##  I/O interface
+
+The I/O Interface provides a simple means of connection to Water Linked products. It provides power and connection interfaces for Water Linked sensors during development. 
+
+It utilizes the Molex Micro-Fit 3.0 power connector (Part number: 436500228). Female connectors are listed under [Mates with Part(s)](https://www.molex.com/en-us/products/part-detail/436500228#mates-with-use-with).
+
+There currently exist multiple revisions of the I/O Interface. Revision 2 and 3 are electrically identical. Revision 4 has an integrated USB-to-UART interface and a micro USB port. Revision 6 has upgraded connection options, including screw terminals and RS-232. 
+
+I/O interfaces have the part number WL-31014-X, where X is the revision number.
