asm330lhhxg1 works at VDD/VDDIO=1.8V but does not work if VDD/VDDIO set to 3.3V

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.
