1. Brief Description
The WF-M620-RSC1 IoT module is based on the MediaTek MT3620AN,a highly integrated single chip,tricore WIFI
MCU designed to meet the requirements of modern robust internet-connected devices.It leverages the Microsoft Azure
Sphere security architecture to provide an unprecedented level of security to connected device manufacturers.For the
lifetime of the device the Azure Sphere system provides device authentication and attestation,supports remote
over-the-air software updates to maintain security in the face of evolving attacks,and automates error logging and
reporting.
