I'm trying to use your module on raspberry pi 3b+ under Raspbian Buster with desktop !

I obtain : OSError: [Errno 121] Remote I/O error

Vin = 5V GND = GND 1V8 = 1V8 SDA = SDA SCL = SCL

imu = ICM20948(i2c_addr=0x68)

I'm sorry. The problem became from the power supply (1V8)...

Thanks for your works
