Figure 1-1 shows the inputs, outputs and power connections for the EB-GS2972.

1.1 Power (J1)
The EB-GS2972 requires a 5V DC power supply. The board is powered through
J1.
LED (D7) indicates the power on/off state of the board.
Through the use of JP7, the user can select the I/O voltage to be either 1.8V or 3.3V.
If the EB-GS2972 and the EB-GS2970 are connected together, one supply will power
both boards. Therefore, the +5V DC power is only required on either the EB-GS2972 or
the EB-GS2970.
1.2 Switch Settings (SW6 & SW7)
DIP switches (SW6 and SW7) are populated on the board with each bit labelled on the
silk-screen. They are used to set the operation mode of GS2972.
