SK200Pro : 5W Industrial MESH Network LoRa Wireless Switch Module

SK200Pro is a 5W industrial wireless switch module. It consists of SK200PRO-TX ( transmitter module ) and SK200PRO-RX ( receiver module ). The wireless design uses LoRa technology, which has highly efficient receiving sensitivity and strong anti-interference performance. Its communication distance and receiving sensitivity are better than FSK and GFSK modulation. In the one-to-many working mode, in cooperation with the MESH ad hoc network that comes with the receiving end, it can form a network transmission without blind spots and distance restrictions.
The module provides single signal input and single control output interface. It has the characteristics of simple interface and reliable operation. Users can combine our PC interface to configure and modify the internal parameters of the module. The parameters of the receiver can be wirelessly configured by the transmitter, which is convenient for online changes. Multi-pair simultaneous communication will not interfere with each other, and it is flexible and convenient to use.
SK200PRO strictly uses lead-free process for production and testing, and meets RoHS and Reach standards.
