Hi,
It would be useful for IoT applications. I think many users are planning to upgrade from the LPC55xx family to the MCX. We are currently modernizing the IoT laboratory at our University (University of Applied Sciences in Tarnow) and we have already purchased a set of EV boards MCX A and MCX N for teaching - we need to connect our WiFi modules. So far we are using EV Boards LPC55s69.
Regards
Daniel
