WebOpen-drain refers to a type of output which can either pull the bus down to a voltage (ground, in most cases), or "release" the bus and let it be pulled up by a pull-up resistor. In the event of the bus being released by the master or a slave, the pull-up resistor (RPU) on the line is responsible for pulling the bus voltage up to the power rail. WebBut the accumulated resistance must be taken into account. Many I2C devices mounted on a breakout board have pull up resistors. Typically these are around 5K Ohms.
