3.3 External Power Supply Header (J5)

To measure the power going to the WBZ351PE Module, a 1x3, 2.54 mm male pin header with shunt connector (I-MEAS, J5) is provided. A shunt resistor (R36) across the jumper is also provided, which gives a relationship between the voltage drop and current consumption. For current profiling in terms of voltage using a voltage probe, mount R36 and measure the voltage drop across the shunt resistor.
