1.2 Features
The new LoRa spread spectrum modulation technology developed based on LLCCGS, it brings a longer communication distance
and stronger anti-interference ability;
Support users to set the communication key by themselves, and it cannot be read, which greatly improves the confidentiality of
user data,
Support LBT
function, monitor the channel environment noise before sending, which greatly improves the communication
success rate of the module in harsh environments,
Support RSSI signal strength indicator function for evaluating signal quality, improving communication network, and ranging;
Support air wakeup, that is, ultra-low power consumption function, suitable for battery-powered applications;
Support fixed-point transmission, broadcast transmission, channel monitoring,
Support deep sleep, the power consumption of the whole machine is about 5uA in this mode;
The module has built-in PA+LNA, and the communication distance can reach 10km under ideal conditions;
The parameters are saved after power-off, and the module will work according to the set parameters after power-on;
Efficient watchdog design, once an exception occurs, the module will automatically restart and continue to work according to the
previous parameter settings,
Support the data transmission rate of 2. 4k~62.5kbps,
Support 3.0~5.5V power supply, power supply greater than 5V can guarantee the best performance;
Industrial standard design, supporting long-term use at -40~+85°C,
SMA antenna interface.
.3 Application
Home security alarm and remote keyless entry;
Smart home and industrial sensors;
Wireless alarm security system;
Building automation solutions;
Wireless industrial-grade remote control;
Advanced Meter Reading Architecture (AMI);
Automotive industry applications.
