WebWhen using I2C to interface from the BeagleBone to an I2C device, the key things to be aware of are as follows: I2C signals are open collector. This allows multiple devices to be connected in parallel. However, this requires two resistors, roughly from 1000 to 4700 Ohms that connect each of the I2C signals to 3.3V.
