Note:
There are two versions of 8773E daughter board, one is the old version with 4ADC pins,
and the other one is the new version with 4 ADC pins. Therefore, it is necessary to note
that the silkscreen on the mother board matches with the new version. The
corresponding relation is as follows.
Besides, if the silkscreen on the daughter board is V7 or above, you can ignore the note
above because the pins of daughter board match with the silkscreen on mother board.
