Parameters

Q&A
Q: What is the UART hardware module?
A: It is a module that can be used for wireless communication through the serial port. Users do not have to worry about its simple wireless parameters, but only need to send and receive the data that needs to be processed through the serial port, which greatly reduces the development cost of wireless communication and shortens the cycle time.
