Product overview
      Based on Lora spread spectrum RF chip and efm32 single chip microcomputer, it supports UART half duplex transparent transmission and star type low-power networking applications. It has ultra-high receiving sensitivity and strong anti-interference ability. Under the same transmission power, the communication distance is longer than other wireless schemes. At the same time, it has the functions of wireless wake-up and ultra-low power consumption, which is convenient for docking various wireless intelligent control system applications of Internet of things.

The usage of pe13 pin in each mode of the module
Working mode Pe13 level input Function module
Normal mode central mode High level At this time, the current of rfu3.9ic is only the depth of the module. The module can not receive serial data and wireless data.
Low level The module is awakened and restored to its original state.
Node mode High level The module is in the alternate state of dormancy and CAD detection. The module can receive air data, but not serial data.
Low level Can receive serial data.
Note: after the pe13 pin is pulled down for 50ms, the module can receive the serial port data. No matter in which mode the parameter is configured, pe13 must be grounded.
