3.5 INA219 Jumper Settings

Figure 3-3 shows the default jumpers configuration for the INA219EVM. Generally, the jumper settings of the

the INA219_Test_Board to match your specific configuration. For instance, you may wish to set a specific I
address.
Table 3-1 explains the function of the jumpers on the INA219_Test_Board.
