OK - thanks.
Is that a change, then?
The DV3 (10 Jan) schematics say, "MT7697IDN" (although that order code isn't listed in either the MT7697 or the MT7697D datasheet)
From the MediaTek website:
MT7697D key features
The difference between MT7697 and MT7697D is that, MT7697D supports additional features below:
IEEE 802.11 a
So I guess the 'D' is for "Dual-band" ... ?
