3. Interfaces
This section describes the features and functionalities of the available host, peripheral, debug, and RF test interfaces.
3.1 Host Interfaces
There are three available host interfaces one of which can be used to connect an external host, typically an MCU, to the WGM110 Wi-
Fi Module and use it as a Wi-Fi modem.
3.1.1 UART
UART is one of the available host interfaces on the WGM110 Module, and it is also the default host interface for the WGM110 Modules
delivered from the factory.
The table below shows the features of the UART host interface:
