+	TeleMega v2.0 has a few minor changes from v1.0:
+
+	* Companion connector matches EasyMega functions
+	* Serial port connector replaced with servo connector with
+	  support for up to 4 PWM channels.
+	* Radio switched from cc1120 to cc1200.

 	=== TeleMega Screw Terminals
 
 		TeleMega has two sets of nine screw terminals on the end of

 		TeleMega provides explicit support for an external pyro
