Using a voltmeter
The EVK board must be modified before module current can be measured with a voltmeter.
To modify the board, solder a low resistance, high tolerance, 0402 sized resistor to the footprint
labeled R6. This resistor replaces the jumper normally positioned between J22 pins - 1 and 3, and any
current running through it produce a voltage across its terminals. Measure this voltage with the
voltmeter and calculate the current using O

s law.
