S2GO MEMSMIC IM69D | Boards with two high-performance digital MEMS microphones and ready to use Arduino library

Overview

Infineon’s Shield2Go boards offer a unique customer and evaluation experience – the boards are equipped with two High-performance digital MEMS Microphone IM69D130 and come with a ready to use Arduino library. Customers can now develop their own system solutions by combining Shield2Go boards together with Infineon My IoT adapters. My IoT adapters are gateways to external hardware solutions like Arduino and Raspberry PI, which are popular IoT hardware platforms. All this enables the fastest evaluation and development of IoT system.
