Communications through universal asynchronous receiver/transmitter (UART) serial ports is convenient and reliable. UART serial ports are widely adopted in Huawei modules. This design guide describes the serial port specifications of Huawei modules and provides recommended design schemes for peripheral circuits. When designing UART serial ports for Huawei modules, customers can refer to this document.

Most of Huawei modules provide 8-wire serial ports with flow control. These 8-wire serial ports can also be used as 2-wire or 4-wire serial ports.
