Figure 19. FXOS8700CQ combo sensor circuit

FXOS8700CQ requires above 2.0 V to work. Make sure that DCDC software driver is configured to supply such
voltage. DCDC software driver is part of the FRDM-KW36 SDK.

NOTE

3.6 Thermistor

One thermistor (RT1) is connected to a differential ADC input (ADC0_DP0 & ADC_DM0) of KW36 for ADC module evaluation.
