Hi @arifkhan ,If the ASM330LHHXG1 sensor works correctly at 1.8 V for VDD/VDDIO but fails at 3.3 V, possible causes include:Power supply stability: Check for noise or voltage dips at 3.3 V that might affect the sensor.IO level mismatch: Ensure your MCU or interface logic levels are compatible with the sensor’s VDDIO voltage.Incorrect wiring or configuration: Double-check power pins and decoupling capacitors for the 3.3 V setup.

Hi @arifkhan ,

If the ASM330LHHXG1 sensor works correctly at 1.8 V for VDD/VDDIO but fails at 3.3 V, possible causes include:

Power supply stability: Check for noise or voltage dips at 3.3 V that might affect the sensor.
IO level mismatch: Ensure your MCU or interface logic levels are compatible with the sensor’s VDDIO voltage.
Incorrect wiring or configuration: Double-check power pins and decoupling capacitors for the 3.3 V setup.
