Current measurement is a crucial feature of any energy monitor based equipment, either in the case of domestic applications or for building energy management systems. This work presents the design and technical features implementation of an expansion board, used to increase reading capabilities of electrical current measurement sources. Using a single microcontroller, it uses Inter-Integrated Circuit communication (I2C) to increase the number of analog reading channels. With this expansion board, an entire electrical frame with several circuits can be read without the need of additional microcontrollers and their associate communication network, with the advantage of adding plug and play capability.
