, ADC exp can have 0x48 or 0x49 addresses(settable).
If is is configure for gpio, change to omega2-ctrl gpiomux set i2c i2c
Please verify that i2c pins are configured for i2c (not for gpio), in the omega2-ctrl gpiomux get 'The Omega2 Dash is compatible with the existing ecosystem of plug-and-play Omega2 expansions.' Still, going though various docs makes me believe that ADC Exp should work with Dash.
