connects to the JP1 male connector on the I2C demo board 2005-1 as shown in
Figure 1 .
With both boards facing you, with USB connector on the left-hand side as shown in the
Figure 1 , connect the OM13333 board to the I2C demo board 2005-1 before connecting
the USB cable. Once the board is connected, connect the USB cable and start the
