# I2C devices
|
|
|
|
Tasmota supports several I2C devices but to use them they mostly need to be enabled at compile time to solve possible address conflicts.
|
|
|
|
Using command ``I2cDriver`` individual drivers can be enabled or disabled at runtime allowing duplicate I2C addresses at compile time. Use the Index from the table below to control I2C drivers like ``I2cDriver10 0`` for disabling BMP support.
|
|
|
|
## Supported I2C devices
|
|
The following table lists the supported I2C devices
