4.5. UART Interface (J301) 

 

The UART interface of the Mini PCIe-C EVB is intended for the communication between the module and 

the host application. It can be used for data transmission and AT command communication. 

 

The following figure shows the block diagram of the UART interface on Mini PCIe-C EVB.
