I am connecting a RP2040 to a Level shifter that connects to a I2C expander (At the very bottom) that receives data from a sensor. Running the set up with other boards works fine but not with the nano RP2040. Please help! Here is a picture. Also I am using the Mega 2560 5V to power the I2C expander chip.
Connecting one single sensor to the I2C on the nano board works fine.
Thank you in advance
