In the case of a I2C single Master – single Slave configuration, a series resistor is recommended to be placed close to the Master device. For all other configurations, series resistors are placed close to each of the Master / Slave device connected to the bus. Refer to the (I2C Bus Specification user guide) to choose the right value for series resistors and corresponding pull-up resistors.7 K- J, ^) f8 Y; _1 O; b8 K$ F
