<![CDATA[M5 Stack ADS1115 address]]>Hello, can I somehow change the address of ADS1115 at my own risk (soldering)
I need 0x4a or 0x4b
0x49 is already occupied, cannot be changed!

check the ADS1115 datasheet (linked here under Related Link). Section 9.5.1.1 I2C Address Selection describes how to change the I2C address.

Looking at the board of my AMeter I can see that it is partly prepared to select a different I2C address. One can move a 10 k resistor from one location to another to switch between 0x48 (default) and 0x49. To select 0x4A or 0x4B requires a bit more work, I am afraid.

Below picture illustrates my modification to change the AMeter I2C address to 0x4B.
