1 GENERAL OPERATION
1.1 PINOUTS
1.2 POWER PINS
• DVDD – 3.3V Power Supply Input
• GND – Ground Pin for Power and Logic
• R7: The current draw from the sensor can be measured by putting an ammeter in
place of R7.
• In the following demonstration, an Arduino DUE is used to illustrate on how to test
the evaluation board with a microcontroller.
• Please be advised that if an Arduino UNO is used instead, hardware modification
on Arduino UNO MUST be made for it to output at 3.3V. (WARNING: attempting to
power the part at 5V is likely to damage it.)
By default, Arduino UNO operates at 5V, which is higher than the maximum
voltage rating for the evaluation board. Please refer to an excellent tutorial on
modifying Arduino UNO to output at 3.3V:
