yes there are. the intent was to detect rotation afaik. one accelerometer is 45° tilted rotated to the left, directly behind the aux button. the other one is mounted horizontal in the lower right corner below the display and right of the mic. you can see the distance is kinda maximized and the '45° rotation' between the 2 accels comes afaik from some recommendation of a datasheet if i remember correctly. something about maximizing resolution and compensating one of the 3 axis having one bit less resolution. one can see both accelerometers quite easy when the front cover of the fr is removed. (lcm side, no need to dissassemble further) left of the reciever-speaker contact pads is the rtc battery and then the accel and the aux key. on the other end of the moko you can see the mic in the middle and the accel right of it. yes, its these small black rectangular boxes with 12 pads. about 5x2.5mm kind regards -- Joachim Steiger Openmoko Central Services _______________________________________________ hardware mailing list [email protected] http://lists.openmoko.org/mailman/listinfo/hardware
