If the ADSP-BF706 EZ-KIT Mini is acting as a USB host through con-
nector and needs to supply power to a bus-powered device, install
P8
to allow the appropriate bulk capacitance.

Power Measurements

Locations are provided for measuring the current draw from various power
planes. Precision 0.051 ohm shunt resistors are available on the
and voltage domains. To measure current draw, the correspond-
VDD_EXT
ing jumper is removed, voltage across the resistor is measured using an
oscilloscope, and the value of the resistor is measured using a precision
multi-meter.

voltage and resistance are measured, the current is calculated by dividing
the voltage by the resistance. For the highest accuracy, use a differential
probe for measuring the voltage across the resistor.
