4.3 Peripherals Interface
WSL05-A0 module provides external interfaces such as UART and SPI. UART0 and SPI
interface that can be utilized as communication interfaces for data exchange, UART1 port is
used as debug interface which can print debugging information.

UART_TX pin, serial data output
WSL05-A0 does not support RTS and CTS functions for the time being.
By default, the UART interface is used as the communication interface with the user's
host.The module may be forced to enable it after power-on or reset. In the case where the
