This module is thinner than the usual. Standard I2C address is 0x20. It is not immediately visible, but A0,A1,A2 are physically connected to low. So to set up a different address you have to cut the connection, and solder desired pin to high. Also it is using nonstandard addresses, so instead of the original liquidcrystal i2c library you have to use this: https://github.com/t3chguy/LiquidCrystal_I2C_GY
