VL53L9 i2c address

I'm trying to start working with Evaluation board based on VL53L9CX Time of Flight sensor
In I2C, I'm having a problem with identifying the component address
I find address 55 and not 29
The connection looks like this
GND to GND
SDA to SDA
SCL to SCL
XSHOUT to 3V3
3V3 to 3V3
I removed resistor 25 for internal clock

According to the datasheets, it seems that 55 is the EEPROM ID

Do you use 8-bit address? the 29 shift one bit should be 52-53

Hi:

As Richard said, 0x52 should be ok.
