Description
Overview
Equipped with a USB to TTL to serial port (which can be used as a regular serial module), this is very practical and greatly convenient for product debugging. It is commonly used for printing debugging in official processes. The board can directly use a data cable to connect to a computer to use serial, and the TXD and RXD pins of the serial chip are also introduced from the board. This way, the board can still be used as a regular serial module, just turn off the board switch. The module is now a regular serial module, and one module is used as two modules. Try to be compatible with official processes and boards as much as possible: In addition to adding additional functions, our board circuits also try to be compatible with official application circuits and processes, which better integrate circuits and processes and are very practical.
