Notes:

All resistors 1/4W unless otherwise specified. Some reference designators

are skipped (e.g. C2, C12, etc.) and do not appear on the schematic.

These designators were used in previous revisions of the board and are

not used on this revision. Additional information on key components is

included in the attached appendix.
