The LCD found on the AVRRAVEN module is a full custom 160-segment display tailored for the RZRAVEN kit (See Figure 3-1 for a quick reference). It contains a 7 segments text area; four segment number area and numerous handy symbols. In particular pay attention to the bird looking symbol. It is symbolizing the two black scouting ravens of Norse god Odin; Hugin (Thought) and Munin (Memory). The saga says that they flew around the world and reported news back to Odin at night. Underneath the raven segment's "eye" there is a red LED capable of soft-blinking; this may be used to indicate the AVRRAVEN's search for "news" on the air interface. A full segment map can be found in Appendix C and in the schematics folder in the compressed archive file accompanying this application note. The LCD is driven directly from the connected ATmega3290P.
