What it does
Implements IDekiI2C plus an I2CBusComponent you place in the prefab to declare which bus pins, frequency, and pull-ups the board uses. Multiple peripherals on the same I²C bus share that one component, so the bus is initialised once and re-used.
This shared-bus model is the reason GPS, RTC, IMU, touch, and any number of other I²C peripherals can coexist on an ESP32 without exhausting GPIOs or re-initialising the bus per peripheral.
