Pictures of NXT Production Hardware

Here are some pictures of the hardware of a production NXT.

View of the top side of the NXT mainboard This is a view of the top of the motherboard. According to the schematics released by LEGO the part missing in the upper right was a battery current sensor on AD5. The black smudge at the square speaker connector covered an additional part in the speaker cable, a 10 Ohm resistor which is not in the schematics. I unsoldered it together with the speaker cable to get the LCD daughter board out of the way for photographing the motherboard.
