3.5 INA230EVM Default Jumper Settings
Figure 8 shows the default jumper configuration for the INA230EVM. In general, the jumper settings of the
SM-USB-DIG Platform do not need to be changed. You may want to change some of the jumpers on the
INA230EVM board to match your specific configuration. For example, you may wish to set a specific I
2
C
address by configuring J3-J6.
Figure 8. INA230EVM Default Jumper Settings
Typically, jumper 2 on the INA230EVM is always set to the INT position. When set to the INT position, the
SM-USB-DIG Platform provides the supply for the INA230. When this jumper is set to the EXT position, an
external supply voltage can be connected to terminal strip T2 to provide the supply for the INA230.
Jumpers 3 through 6 control the I
2
C address pins for the INA230. These jumpers can set the address for
A0 and A1 to either supply, ground, SCL, or SDA. Make sure to only connect one jumper at a time for
each address control. Failure to properly connect jumpers can cause shorts or interruptions in the
communication lines. For more information on the INA230 addressing, refer to the INA230 product data
sheet.
Table 4 summarizes the function of the INA230 Test Board jumpers. For most applications, all jumpers
should be left in the respective default configurations.

Jumper Default Purpose
J2 INT This jumper selects whether the V
S
pin
on the INA230 is connected to the V
DUT
signal generated from the SM-USB-DIG
Platform or whether the digital supply pin

DUT
control signal.
