Chip listing:
- U1:
- U2:
- U3: ST Microelectronics M24128-BWP - "412A" "BWP" (128kbit I2C eeprom - tssop-8)
- U4: Analog devices ADXL330 - "XL" "330K" "#0614" "3464P" (accelerometer - 16 pin LGA)
- U5: suspected to be Microchip TC1027 - "628" "3322" (quad comparator -16 pin QSOP) - could possibly be a Mitsumi chip (the logo is similar)
- U6: Unknown manufacturer - "U7849" "6Q19" (Likely Audio DAC chip, due to proximity to U7 Speaker amp, and lack of another chip to perform this function - 16 pin tsop)
- U7: Rohm BH7824FVM - "H78" "2 4" "HN" (audio driver (speaker AMP) for mobile telephone - MSOP-8)
- U8: Broadcom BCM2042 - "BCM2042KF8C" "C80830 P13" "788899 N1" (Broadcom bluetooth & 8051 - probably 88pin FBGA)

Other interesting things:
- Crystal Y1, likely 24MHz as per [Sparkfun's wiimote page] (they got a shinier crystal than I did)
- CCD Camera at the front of the PCB (8 pins, no distinguishing characteristics.)
- Rumble motor off-board via wires (labeled "SEM 6923FB")
- Large electrolytic capacitor (3300uF)
- Connector at the base for nunchuk, classic, etc.. (6 pins)
- More information on the Wiimote's attachment connector can be found at the Wiimote Accessory Bus page.
- PCB is certainly more than 2 layers - probably 4 layer.
- PCB has some text possibly marking the revision - "MDK 332V-0" followed by a small "N"
- There are 3 fuses on the "top" of the PCB. (one larger one, and 2 smaller ones)
- U1 and U2 are piddley little logic/transistor/voltage regulator ICs, U1 is 4 pins, U2 is 5 pins, and their captions are essentially meaningless.
