Table 5-1. Sensor I
A number of hardware options are available on the Inertial Two Sensors Xplained
development board to allow investigation of the sensors’ functioning. Theses options
are described below.
The power supplied to the digital header on the Xplained series of sensor boards is
nominally set to 3.3V. The Inertial Two Sensors Xplained development board has an
onboard 2.5V regulator to supply power to all three sensors. The current from the
regulator is supplied to the sensors through R3, a zero-ohm resistor. This resistor can
be removed and replaced with a current monitor, if required, to investigate the sensor
power consumption. If it is desired to bypass the onboard regulator, R3 can be
removed and a zero-ohm resistor placed in position R4. This will now supply the
sensors directly from the 3.3V Xplain MCU board supply.
A number of test points are available for use with an oscilloscope to investigate the
functioning of the sensors.
