Apollo3 Blue Plus EVB Quick Start Guide
Ultra-Low Power Apollo MCU Family
As an example for setting the jumpers on P19, Figure 7 shows the EVB configured for 3.3V operation with
jumper across VDD_PS and VDD_MCU for no current measurement.

Figure 8 shows the EVB configured for 3.3V operation with current measuring leads across VDD_PS and
VDD_MCU for current measurement.

Measuring the current consumption of the target MCU on the board using equipment with a sensing
resistor will create a burden voltage over the resistor on VDD_MCU. In some cases the burden voltage
may be too high and may cause a brown-out event on the target MCU at 1.8V. SB1 on the board can be
