I was dissecting an old Sansa Clip<V2>, just now and you wont believe what I found!
The layout of the board includes an area for a ceramic antenna!
I was shocked because ceramic antennas are use a lot in portable RF transceivers and transmiters but not much in receivers. I don't know if this means anything, but it would seem like a waste of space to put another antenna in the design if the Sansa Clip is only a receiver....
Sansa clip v 1 & 2:
The 'place holder' is located between the two volume control switches near a chip marked: (0219 ccpz 834). No idea what the 0219 chip is for though...
And yes I realize this topic is old.
