The NAFE33352-UIOM universal AIO AFE Arduino shield board is easy to test and designed for the NAFE33352, which is a highly configurable, industrial-grade universal analog input and output front-end (AFE). This Arduino shield board enables compact hardware design and enhanced software configurability with universal open-CMSIS driver packs.

The shield board supports quick evaluation and plug-and-play compatibility with NXP MCU boards (MCX-N and LPC) having Arduino connector. Users can quickly generate analog output (voltage/currents) and perform voltage, current and temperature measurements (RTD and thermocouple), reducing the development time of the final application.
