Getting Started
This is a simple module that only needs to connect the corresponding interface to the corresponding device
to transfer data using the serial port tool. You should note that when connecting a TTL device, the RX pin of
the module needs to be connected to the TX pin of the device, and vice versa, the TX pin of the module needs
to be connected to the RX pin of the device.
