RXD in the application side will be connected to the transmit line (here named C104/RXD)
NOTE:
For minimum implementation, only the TXD and RXD lines must be connected, the other lines can be
left open provided a software flow control is implemented.
NOTE:
In order to avoid a back powering effect it is recommended to avoid having any HIGH logic level
signal applied to the digital pins of the UE910 V2 when the module is powered off or during an
ON/OFF transition.
NOTE:
High-speed UART supports up to 4Mbps. Please refer to the AT command User Guide in detail.
WARNING:
Consider a mechanical design and a low-capacitance ESD protection device to protect UE910 V2 or
customer specific requirements from ESD event to UART port (M15, N15, P15 and L14).
