Why is the touch interface on the SK-S7G2 V 3.0 kit not as responsive as I expect?

Latest Updated:10/13/2016

Question:

Why is the touch interface on the SK-S7G2 V 3.0 not very responsive?

Answer:

The capacitor used on the SK-S7G2 V 3.0 kit (C63) for TSCAP should be 10nF but a 100nF capacitor is used instead. This makes the charging time longer and less responsive. It is still usable, but it can be noticible in some applications. This is being fixed in the Rev 3.1 version of the board scheduled for release in the May/June timeframe.
