This component sets up the I²C bus for your ESP32, ESP8266, RP2040 or NRF52. In order for these components
to work correctly, you need to define the I²C bus in your configuration. Please note the ESP
will enable its internal 10kΩ pullup resistors for these pins, so you usually don't need to
put on external ones. You can use multiple devices on one I²C bus as each device is given a
