PCA9956B demonstration board OM13321

4.3  OM13321 connection to WIN-I2CUSB hardware adapter board

The Win-I2CUSB board should be disconnected from your PC before connecting the 
OM13321 board on to it. The OM13321 board has a 14-pin male connector (CON4) that 
connects to the 14-pin male connector (J1) on the Win-I2CUSB board as shown in 

Figure 2

.

Connect the OM13321 board to the Win-I2CUSB board before connecting the USB cable. 
Once the board is connected, connect the USB cable and start the WIN-I2CUSB Lite 
software. You are now ready to evaluate the PCA9956B.
