The I2C 2005-1 demo board should be disconnected from your PC before mounting the
OM6281 board on to it. The OM6282 board has a 9-pin female connector that connects to
the JP1 male connector on the I2C 2005-1 board.
With both boards facing you, connect the OM6282 board to the I2C 2005-1 board before
