Add Note Edit Step 10

  • At the heart of the Magic Trackpad's logic board lies a Broadcom BCM2042 for Bluetooth connectivity.

    • This is the same chip used by the Magic Mouse for data transmission.

  • We found a Broadcom BCM5974 touch screen controller chip that provides Multi-touch functionality.

    • This is the same chip you'll find in the iPhone, iPod Touch, and MacBook Air.

  • Also, an SST 25WF020 provides 2 Mbit of serial flash memory.

  • This appears to be a TI CD3238, which has been identified by Hearst as a RS232 line driver/receiver. It was also in the original iPhone with a BCM5973A.

  • The back of the logic board features nothing but blackness and glue.
