INA230EVM Hardware Setup
shows the overall system setup for the INA230EVM. The PC runs software that communicates
with the SM-USB-DIG Platform. The SM-USB-DIG Platform generates the analog and digital signals used
to communicate with the INA230 test board. Connectors on the INA230EVM test board allow the user to
connect to the system under test conditions to monitor the power, current, and voltage.
