Preparing for VBUS current measurements

You can prepare the Evaluation Kit (EK) for measuring VBUS current based on different scenarios.

To prepare the EK:

• To use P1 as a probe-point for performing current measurement on VBUS, cut the PCB track shorting solder bridge SB3.
• To use an oscilloscope for measurements, mount a series resistor on R1. The recommended resistance value is 100 mΩ.

To restore normal kit functionality after measurements, solder SB3, add a 0 Ω resistor on R1 or apply a jumper on P1.
