2.5 Measure Current Consumption

To measure current consumption, remove the JP1, JP2, or JP3 jumpers and place an ammeter across the header pins. Connect this jumper when not performing current measurements. Figure 3 shows the location of JP1, JP2, and JP3. Table 1 lists which power rail to measure on each jumper.
