The LoRa II module is a new series of upgraded networking wireless communication modules from NiceRF. It uses advanced LoRa spread spectrum modulation frequency hopping technology to achieve high sensitivity. The penetrating power and communication distance are far superior to the current FSK and GFSK products, and have stronger anti-interference. In order to meet the application needs of different customers, we design the module software of this series as an all-in-one way. Users can switch between different working modes through the PC software configuration module. In MESH mode, the routing module has automatic routing. Function, the user can form a network transmission without blind zone without distance limitation by means of multi-module combination. At the same time, users can also encrypt AES128 wireless data through PC software or serial port instructions, making data transmission more secure.
The LoRa6100II module is designed for 1W output power under the power supply of a single-cell lithium battery, and embedded small size design, which is widely used in wireless remote transmission control industries.
LoRa6100II strictly uses lead-free process for production and testing, and meets RoHS and Reach standards.
Note: The module is internally regulated by 3.3V LDO. The CS pin and SET pin control are 3.3V levels. TXD and RXD are also 3.3V levels.
