    • On MP1, AC Adapter is moved to the expansion board, which is included in the bc10 set, and
      the USB mini B connector on the expansion board is used for power supply.

30-pin Connector †

• List of signals that 30-pin connector (the picture of Main Board Front View No.8) handles
  • Stereo Audio Input
  • Stereo Audio Output
  • S-Video/Composite Video (Exclusive)
  • Serial Console
  • Power Switch
  • USER Button
  • RESET Button

• To handle several output signals simultaneously, use an iPod/iPhone connector, which is differ from commercially
  available iPod/iPhone accessories. Wire the specified pins through the connector. To control the power switch and
  reset button of bc10 externally through the 30-pin connector, please make sure that the switch at bc10 turns off.
  This is a two-part example, which shows how to connect serial console and how to control external RESET and USER
  buttons, and power switch simultaneously. The example is listed here (making a serial interface) and here (adding
  external buttons and power switch to the interface).

• Caution: all 30-pin connecters are neither identical nor compatible. Commercially available iPod/iPhone accessories
  should not be connected with this 30-pin connector of bc10 in general. It is true that some accessory may work with
  the 30-pin connector as some pins and functions are for bc10, but it is very seldom and requires a lot of homework
  before connecting the two products. Do not connect the accessories which employ the function of Firewire, these
  accessories may damage bc10.

Slot for Expansion Board †

• List of signals, which both slots (the picture of Front View #12) deal with
  • GPIO
  • Keypad
  • UART1
  • I²C (2ch)
  • SPI (1ch)

• The signals of GPIO and keypad are not shared between the right and left slots. The right and left sides of these ports
  are designed to be independent from each other. Other output signals are share between the right and left slots.
  
• Slots for Expansion Board output the signals at 1.8V CMOS level. If a board connect with the slot at other than 1.8V,
  it requires a logic voltage level converter to adjust voltage.
