The LoRaII module is the latest series of upgraded network wireless communication modules launched by Think for Wireless. It is developed based on Semtech's LLCC68 chip and utilizes advanced LoRa spread spectrum frequency hopping technology. With its efficient receiving sensitivity, it greatly surpasses current FSK and GFSK products in terms of penetration capability and communication distance, and exhibits stronger anti-interference properties. To cater to different customer needs, we have designed the firmware of this series of modules in a multi-functional, selectable manner. Users can switch between different working modes through PC software. In MESH mode, the routing modules have an automatic routing function, allowing users to form a network transmission with no blind spots or distance limitations by combining multiple modules. Additionally, users can encrypt wireless data with AES128 through PC software or serial port commands, ensuring more secure data transmission. The LoRa611II-DZ module is designed with a 160mW output power and a compact embedded design, finding widespread application in industries requiring wireless remote transmission control. The LoRa611II-DZ strictly follows lead-free manufacturing and testing processes, complying with RoHS and Reach standards.
