3.4 Connecting the Hardware

To set up the INA233EVM and connect the two PCBs of the EVM together (that is, the INA233 test board and SM-USB-DIG Platform board), gently slide the male and female ends of the 10-pin connectors together. Make sure that the two connectors are completely pushed together; loose connections can cause intermittent operation. Figure 3-3 show the proper orientation.

Lastly, connect the SM-USB-DIG to the computer, using the included USB extender cable. At this point the SM-USB-DIG powers on, but the EVM does not as shown in Figure 3-4. The power supply to the EVM must be enabled from the GUI.
