YH: C5 C. Cap 10uF type, due to the defec tive rate of
the package 0805. Suggest to use 1206 package.
AP: Ok
YH: Because use the same AD49 keybed for ADW1,
these 2 connectors should be with 16pin connector,as
for their key scan net definition, please refer to AD49.
AP: No. This is same circuit as AD4A, and we want
these to be the same.
