OSEPP I²C Expansion Shield for Arduino "walkie talkie" even those found in largeThe OSEPP IC Expansion Shield is an Arduino compatible daughter (extension) card. This shield provides easy interconnection with other IC devices, such as the OSEPP Sensor Modules family. Additionally, this shield integrates the PCA9546A IC switch from Texas Instruments that provides 4 additional isolated IC buses to enable the use without collisions of multiple IC devices with same IC addresses. The main IC bus and each of the 4 additional IC buses
